Hyundai - Santafe :: 2013 - Sudden Power Loss When Accelerating From A Slow Speed Coast
Occasionally, randomly, and unpredictably when accelerating from a slow speed coast I get no power response when I press down on the accelerator. It's as if the engine has stalled, but it has not. When the accelerator is held down for a few seconds (maybe 3 to 7) power comes back with a rush. Examples:
1. Making a U turn from a left turn late. Accelerate slowly forward, take foot off gas as the turn is initiated, press down on gas to accelerate out of the turn and get no immediate power response.
2. Making a left turn into a suicide lane. Accelerate to cross 2 traffic lanes, let off gas and coast slowly forward in the suicide lane while waiting for oncoming traffic to clear, traffic clears, press down on gas and get to response. Continue to press slowly down--no response. Hold the accelerator half or 3/4 down, power surges back after a few seconds.
3. Rolling slowly down a long left turn lane with foot off gas timing oncoming traffic, traffic clears, press down on gas to initiate the turn, no response. Let up on gas and press down again, no response, let up an press down again and car reacts normally.
Occurrences of this problem have been very random. I have spent a good deal of time in vacant parking lots trying to cause the problem to occur without any luck even though I know well the conditions under which it happens. I have left the car with the dealer but, of course, they can't observe the problem either. I have driven nearly 1000 miles without an incident and then had 2 occurrences within 4 miles of each other. I have about 5000 miles on the car and have logged 17 incidents.
Loosing power in traffic is, of course, dangerous. I was about to initiate action under California's Lemon Law when I went to England for 3 weeks in Sept. I rented an Audi A1 and to my surprise I experienced a very similar problem, but it happened much more often. An example would be entering a roundabout, letting up on the accelerator while looking at directional signs, reapplying accelerator pressure and getting no response. Unlike the Hyundai I didn't seem to lose all power, but couldn't get any acceleration. The Hyundai engine is the 4 cylinder turbo and has an electronic throttle. I don't know what the Audi had by way of mechanics. I'm at a complete loss; is there something I don't understand about electronic throttles? I don't have a clue about the source of this problem, but I know I need to get it resolved before I get rear ended.
Passat (B5) :: V6 Tiptronic - Momentary Loss Of Power
2001.5 V6 Tiptronic ... A few times in the last couple of months I've felt what I think is a quick lapse in power, like 1 sec. or less. I say "think" because sometimes a bump in the road, traction related, or some other perceived issue can feel strange, especially when cruising along on a smooth cruise-controlled drive.
Each time this has occurred I've been in cruise control, freeway driving, relatively low speeds (65 MPH) . No other signs of anything wrong, chimes, flickering lights, vibration, nothing.
I can't be sure this time around but it seems in the past it's been on the same stretch of freeway, perhaps the same spot. In other words perhaps just a subtle anomaly in the road ...
Jetta - Volkswagen :: 2011 TDI - Momentary Loss Of Power
I have had the car sense it was brand new and sense I have had it I have had this problem. I mostly notice a problem soon after starting the engine up and come to a stop, but is not limited to that all the times. When I come to a stop the car will feel like it is struggling to maintain an idle as I sit at the light or stop sign and it will actually shake the car a bit. I have noticed when it does do this the fan is on and it might be related to having the alternator trying to keep up with power draw.
I have noticed a loss of power when I am driving down the road it will cut out for maybe a half a second and come back. Usually doesn't happen more than once in one trip. I have brought it to the dealership multiple times to try and see if the can hunt down a problem but it keeps coming back with a clean bill of health. So my question is it something that is normal with diesel engines or is it something that I should take a further look at.
And while on the topic of diesel engines, my uncle a mechanic for diesel engines suggested that I spray a small amount of propane into the air intake to burn up sludge to keep the engine relatively clean. Need to get second opinion of that idea before I try it?
Santa Fe (CM - 2007-12) :: 2009 - Momentary Power Loss While Driving
The car started rough idling and a few weeks ago while driving "lost power" momentarily. I went to take a look at it and even just idling it will randomly drop 1000 rpm, or when the gas is one in P it does the same thing. also the dash lights dim at the same time.
I pulled these codes (below). I cleared the codes and tried to replicate with no luck. The car had been sitting in a parking lot outside for a few days and it has been -15C. I asked if it seemed to only happen when it was warm (the week before it was +10C) and they said yes. It has been another week (still cold) and the codes have not returned.
Quick google of these codes suggests maybe a throttle position sensor and/or loose battery connection.
Golf IV R32 :: Hard Acceleration In 3rd Gear / Momentary Loss In Power
Having problems where sometimes the car won't go into gear, other times it's fine? The problem started after some hard acceleration in 3rd, there was what felt like a momentary loss in power. I dipped the clutch as I thought a boost pipe had popped off, all was fine (still seeing boost when revved). After this it got progressively harder to get gears, finally resulting in not being able to get into gear at all.
I found I could get it into 1st with the engine off and could go up gears normally, but couldn't change down without stopping and turning the engine off. The clutch is working fine, the biting point is normal. The problem seams to come and go randomly, it will work fine for a while and then start playing up again. When working the gearbox feels normal, there is no grinding or wining noises. I can move between gears normally and do clutch less gear changes.
There is now a vibration which can be felt at 1000rpm when stationary. It feels like it coming from the engine/gearbox and seems like something is out of balance as it shakes the whole car. The car is on 91k, supercharged running 470hp & 370lb/ft (at flywheel) and is fitted with a Spec stage 3+ clutch and solid flywheel.
Lexus SC430 :: 2002 - Intermittent Hesitation Or Stumble / Momentary Power Loss
When I take off from a start it will intermittently stumble or hesitate, seems to be around 1500 rpm. have also noted it at higher speed while cruising. its more like a momentary power cut than a miss fire.
So far I have done the following
new fuel filters
clean MAF
new PCV valve
new spark plugs
check all hoses and plugs etc
injector clean
checked techstream for codes. there is one for a heated O2 sensor but dont think thats it.

Santa FE SM (2001-06) :: 2004 - Momentary Loss Of Power / Engine Management Light Came On
I have a problem with my 2004 Santa Fe, 2l diesel. Will try to keep this short!
When driving it suddenly 'heaves' (not sure how else to describe it), then it cuts out. I wait about a minute and then it restarts.
At first there was no 'heave' but there would be a momentary loss of power (I thought it was the clutch). Then it progressed to the 'heave' and then cut out, this happened now and then. Very quickly it started to do it every time I drove it. My neighbor mechanic blew down the fuel line, said the fuel pump in tank sounded ok, seemed to do it more when below quarter of tank.
So I kept tank topped up, it seemed ok, then on one 11 mile journey it did it 3 times, the last time the engine management light came on, crawled it home, after which it would not start at all. The computer said it was either fuel rail or coolant sensor. Neighbor replaced coolant sensor, it started ok. Tried it next day - 6 miles and it heaved and cut out again. This time no light coming on.
I've read about cam sensor, crank shaft sensor, fuel pump at back of engine...
Phaeton :: Surging Of Engine / Momentary Loss Of Power At Normal Highway Operating Speeds
The primary electric fuel pump in the fuel tank of my 2004 W12 failed last month, shortly after I had set out on a cross-Canada trip from Vancouver Island to Toronto. The whole process of diagnosing and identifying the cause of the problem, mitigating it so that I could continue the trip, and finally replacing the fuel pump was kind of complex, so, here's the write-up.
The problem presented itself as a surging of the engine - a momentary loss of power - at normal highway operating speeds. The onset was progressive, but it didn't take very long - only about 60 miles of driving - from the first little cough of the engine until total failure of the pump. The first indication was failure of the car to maintain speed (while on cruise control) when climbing hills. That progressed to failure to maintain speed on flat surfaces, and finally led to the car coasting to a stop, engine stalled, at the side of the road.
I soon learned that if I floored the accelerator pedal and held it against the floor, the car would cough and burp for a few seconds, then take off like a rocket. So, for the next 40 miles, I coaxed the car into the next city by flooring it, accelerating to about 80 MPH, then coasting until the speed dropped to 20 MPH, and flooring it once again and accelerating to 80 MPH. Fortunately, I was on a remote road with few other cars, and no police.
I checked the fuses for the two fuel pumps - fuses 34 and 35 in panel C (above the left battery), and they were both OK.
The next day, I visited a VW dealer in the Canadian Rocky Mountains, and together with the parts manager and one of the technicians, we looked at the Self-Study Guides (SSGs) for the Phaeton, and looked at wiring diagrams. Eventually, we came to a tentative conclusion that the primary electric fuel pump in the fuel tank had failed. The SSGs stated that the primary electric fuel pump (the pump on the right side of the car) operates all the time, and the secondary electric fuel pump (the pump on the left side of the car) only operates during starting and during 'periods of high demand'. That made sense to us - the car started fine, and worked OK when the accelerator pedal was held to the floor (high demand). It just didn't work worth a darn at any other time... the engine would stall, or, the car would not accelerate at all.
Here are two illustrations taken from the SSGs that describe how the fuel delivery system works. The first image is taken from the 'Phaeton Overview' SSG, which applies to all vehicles. The second image is taken from the W12 engine SSG. I kind of suspect that all the Phaetons operate in the same way, regardless of engine, because the fuel tank in all the Phaetons has the same shape - two lower lobes, which means two pumps are required.
Descriptions from the SSGs
I think that there may be an error in the description above. My experience suggests that the right hand pump (identified as G6, above) is the primary pump, and the left hand pump (identified as G23) is the one that switches on during starting and periods of high demand. Note also how the identification of G6 and G23 in the illustration above is reversed from what is shown in the illustration below. I believe that the text and illustration below is correct, and the text and illustration above is incorrect.
The 'effects of failure' in the description above would, I believe, make sense if it was the left-hand pump that failed. In my case, the right hand pump failed, and the effects of failure that I experienced were as I set them out in the beginning paragraphs of this post - quite different from the 'effects of failure' of the left hand pump that are described in the SSG above.
After coming to the tentative diagnosis that the primary electric fuel pump (the right hand pump) had failed, we checked the parts stock status in North America. There was one pump in stock, but it was in the United States, and being that it was a Thursday, the pump could not be delivered before the following Tuesday. I didn't want to spend that much time waiting for it, so, we started thinking about other possible solutions.
If we could somehow get the secondary electric fuel pump - the pump on the left side of the car that only operated during starting and heavy demand - to operate, that just might put me back on the road again. So, I removed the plastic cover from the small relay that operates the secondary pump, and wrapped a rubber band around the relay, thus keeping the relay in the closed position. A short test drive proved that this solution worked just fine, the car once again operated normally. The only "problem" was that the last 25% of the fuel in the tank would be unusable, because that fuel would be left behind in the right-hand lobe of the tank - the lobe with the defective primary fuel pump.
Electric Fuel Pump Relays
Here is an illustration from the Phaeton wiring diagrams identifying the various relays above the left battery.
Here you can see the two relays for the electric fuel pumps. They are identical part numbers.
Here you can see the relay for the secondary electric fuel pump, with a rubber band wrapped around it to keep it continually closed.
Aside from the loss of use of the last 25% of the fuel in the fuel tank, the car worked just fine with the secondary electric fuel pump running all the time. There were no problems noted even under heavy acceleration. It was, however, necessary to physically remove the rubber-banded relay from its position in the relay panel whenever the car was shut down for more than half a hour. The power to this relay comes from Terminal 30 (battery direct) - it is not switched on and off with the ignition as Terminal 15 power is. This meant that if the rubber-banded relay was left in position overnight, the left hand battery would totally discharge, because the fuel pump would operate continuously all night. I discovered this the morning after the first night...
So, for the next 8 days, I drove across Canada, removing the relay each night and replacing it each morning. I didn't bother to remove it when I stopped for meals or fuel. The rest of the 3,000 mile trip was uneventful - except once, when I let the fuel tank run down a bit too close to the 1/4 full mark, and the car began surging again because the left hand lobe of the fuel tank (with the functional secondary pump) had emptied out. That was a close call, but I managed to get to a gas station and refuel.
After arriving in Toronto, I called the parts staff at my home VW dealer and ordered a new primary electric fuel pump. I discovered that the left and right hand pumps are slightly different (the various hoses coming out of the pumps are different), and I also discovered that a pump costs about $400. The parts staff suggested I order two seals (one for each side of the tank), because I would have to remove both the right and left fuel tank covers to change the right pump. The seals were not expensive.
Here are two pictures that illustrate where the pumps sit in each lobe of the fuel tank. Note the fuel filler port on the left side of the pictures (as we know, it is on the right side of the car) for orientation.
Phaeton Fuel Tank, showing pumps
Fuel Pump Access Panels
Below is a picture that shows where the access panels to the two fuel pumps are. It's easy to get to these access panels, just remove the carpeted panel from the floor of the trunk.
Here's a close-up of the right side (primary) electric fuel pump access panel.
The instructions (from the VW Repair Manual, or the ELSA / ErWin system) for replacing the fuel pump are quite well written. The repair manual suggests that the fuel tank be drained before replacing a pump. I didn't want to drain the tank, so, I ran the fuel level down as low as I dared (remembering that 1/4 full is effectively 'empty' with a failed primary pump). That proved to be adequate.
There are a heck of a lot of steps involved in disconnecting all the hoses and loosening the various components before the pump can be removed. I strongly suggest that anyone attempting this task have a printed set of instructions before starting disassembly.
The fuel pump has quite a few hoses and connections on it, but fortunately, each connector is unique in design, thus it is not possible to hook things up the wrong way when installing the new pump. It is possible to 'lose' a hose inside the tank... for this reason, I attached a small piece of string to each hose I disconnected from the pump.
The process goes more or less like this:
1) Remove the two 404 relays, to ensure no power is sent to either fuel pump.
2) Lift the rubber cover, and remove the electrical connections from both pumps (left and right).
3) Using a special tool, lift up the three fasteners that hold the cap over top of the access panel (these are NOT threaded fasteners!)
Here is a side view of the three fasteners that hold the plastic cap in place - they are friction fit, not threaded.
4) Now you have a clear view of the access panel. It will probably be dusty and rusty, and should be vacuumed clean before proceeding, to prevent crap from falling into the fuel tank when the cap is removed. The rust is due to condensation forming on the cold metal part whenever the car is filled with cold fuel from an underground storage tank.
5) A special VW tool is used to remove the locking ring from the access panel.
6) After removing the locking ring, I buffed it up with a wire brush to remove surface corrosion.
7) The plastic access cap can now be lifted. There are two electrical connectors on each fuel pump, but three possible fittings on the plastic cap. Fortunately, the three fittings are keyed differently.
8) This is what you see inside the tank after removing the plastic cap.
9) After following all the detailed instructions for disconnecting and stowing hoses, disconnecting the fuel measurement probe from the pump housing, etc., it is possible to lift the pump out. It will be full of fuel.
10) The old and new pumps, side by side. I was very surprised at the amount of crap that was trapped in the filter screen at the bottom of the pump. The car only has 60,000 miles on it, and I have always used premium fuel in it.
11) I was also a bit surprised at the discolouration of the pump components. Below you can see the old and new pumps side by side.
12) It is necessary to get access to the opposite side (in this case, the left side) fuel pump, because hoses from each pump travel horizontally across the tank and connect to the other pump.
13) Here you can see a new hose from the right side pump connecting into a T fitting above the left side pump. It is easy to thread this hose across the top of the inside of the tank.
14) As mentioned earlier, there are three possible fittings on the base of each plastic cap, but only two connectors within the fuel tank. Everything is keyed, thus improper assembly is not possible.
Once the new pump has been installed, the hoses connected, and the fuel measuring probe reset into the side of the new pump, re-assembly of everything is quite straightforward. I replaced the rubber ring around the access panel opening on each side of the tank, and I also buffed up the locking rings using a wire brush (to remove corrosion) on each side.
It was not a pleasant job - your hands get covered in fuel, and there are some hazards associated with working on an open fuel tank with vapour escaping, but it is not a particularly difficult job. It is time-consuming, though.
Ford 7.3L Power Stroke (1999-2003) :: E350 - Sudden Power Loss / Zero Power
I am still failing to appropriately diagnose the problem(s) with my '03 Ford E-350 7.3L Powerstroke. This van has only 69,000 miles on it. A week or two back (just a few days back in work time) it suddenly went from running perfectly smooth, clean and wonderful to this:
- Zero power. Putting the van in gear and flooring the engine causes lots more smoke not nearly any rev of the engine and just a crawl forward.
- Lots of smoke out the back exhaust, whitish. I cannot discern wether it smells like diesel or oil (because I'm ignorant here), but the smell is very strong.
- After warming up and idling ~ 15 min I check under the coolant cap and see no signs of bubbling or disruption (from opening the cap in the coolant tank).
- After warming up there are no warning lights visible on the dash, and I don't have a computer to read codes (if there are any to read).
- I replaced the turbo up-pipes which had a visible leak previously. This did not hurt the symptoms, though no more visual leaks under the dog house.
- I thought maybe I put gasoline instead of diesel in the truck, not so.
- To do the above test I had to use the fuel pump to get gas out the tank to test. I hijacked the fuel pump output and turned the car on a few times to get gas out to a tank. The pump seemed to work just fine.
This was all very sudden which is perplexing, and, in use, the van was previously an ambulette and in my few miles with it (maybe 200-300 only) use was extremely light for such an engine/van, just driving around doing errands. I am not sure if this is relevant (no one has suggested so, yet) but before all this happened I uninstalled the rear HVAC that came with the van when I bought it. The AC lines were sealed under the hood. The coolant line was returned at the doghouse (you can see this at the beginning of the video).
At the moment the van has no power to go anywhere. I have not yet checked the CPS or IPC sensors, and understand this might be the next route in standard troubleshooting?

Ford 6.0L Power Stroke Diesel :: 2004 F250 - Sudden Loss Of Power
I have a 2004 F250 6.0 DuperDuty with about 170,000 miles on it, so far no major break-downs, just a starter and a blinker relay, but now I have a problem.
When I start now, the truck starts fine and it sounds fine, but it has almost no power even if I floor the gas peddle, there is a delay of like 2-3 seconds and then responds slowly, like some tractor. Eventually it starts to move slowly, and after it warms up (after a few minutes), the gas peddle responds more normal.
Also - at about 45mpg, at lower RPMs about 1250, the engine starts to shake (weird), it doesn't do it at idle about 850 RPM, or when I get it up to about 1800RPM+, but at about that 1250 RPM it does do it, luckily I driver locally for a few miles.
What could this be ? What exactly happens when I press on the gas peddle, what systems are involved and in which order?
Ford 6.0L Power Stroke Diesel :: 2004 F250 - Sudden Loss Of Power
I've got a 2004 F250, 6.0, with 150k miles. I was pulling a motorcycle trailer uphill in the mountains when suddenly I couldn't go over 10 to 15 mph. All the gauges read good but it just couldn't get any power.
Got to the top and checked over everything. Didn't see any issues. Drove it home (200 miles) the next day. It drove okay on highway but it felt like the turbo wasn't coming on. Coolant was low and EGR was gunked up but only slightly wet. From what I read, it sounds like EGR cooler is failing but would that cause the turbo not to come on or feel like that loss of power? Reading another thread, I thought it might be the fuel pickup but I dropped the tank and the sending unit looked very good.
I'm ready to throw on a bulletproof egr cooler, oil cooler and rebuild the turbo if necessary but hate to get to the end and find out none of that worked.
Ford Escape / Hybrid :: 2001 XLS - Momentary Loss Of Steering
A couple weeks ago I had to have both lower ball joints replaced on my '01 XLS 4WD with the 6 cylinder engine. The garage's alignment machine was on the blink, so the mechanic told me to it woudl be fine to drive, and to bring it back this week when the machine was fixed.
The Escape seemed to drive fine until today, coming home from work, the Escape veered slightly to the right, and there was a brief sensation in the steering wheel as if it had been disconnected, as if something slipped. Then the steering was back, and although I was tracking straight down the highway, I noticed the steering wheel was turned to the left. It seemed to steer fine, although I had slowed way down.
Ford 6.7L Power Stroke Diesel :: 2011 - Sudden Power Loss - Cylinder 5 Dropped
My 2011 6.7 suddenly lost power, started making noise and then stalled out.
After finding out that there are zero 24 hour service companies available in the LA area, I was able to get it towed to the local Ford dealer.the next day they told me it had dropped the #5 cylinder and that they would have to tear into it to find out what happened.
While I realize that any thoughts on the situation would be primarily idle speculation, what would cause this to happen at only 125,000 miles.
Ford 6.0L Power Stroke Diesel :: 2004 F250 Just Died All Of A Sudden - Intermittent Power Loss
Ok I have an early 2004 F250. Recently changed out the #8 injector and then had to replace the ICP Sensor. Was running great then while driving down the road just died all of a sudden. Would start right back up with no issues. Continue driving and I am getting intermittent power loss. Also noticed that when it would lose power suddenly the glow plug light would come on.
Codes are P0102, P0113, P0272, and P1000.
P0102 Mass or Volume flow circuit low input
P0113 Intake Temp circuit High input
These are just soft codes not setting a light off. MAF is plugged in and I will check wiring here later after work but could this be causing my intermittent issues?
Ford Super Duty (1999-2016) :: Sudden Loss Of Power / Truck Would Not Go Any Faster Than 45 MPH
I am trying to diagnose a problem with a friends 2002 f350 7.3L truck. the engine has approx. 140,000 miles and is all stock, no programming or aftermarket parts. Anyhow, he said driving down the road the other day the engine all of a sudden lost power and the truck wouldn't go any faster than 45mph. he said taking off from a stop sign, the truck has no power and takes forever to get up to 45mph. after this issue began, he has changed the fuel filter & screen, air filter and fuel pump. The check engine light if OFF, no active fault codes.

On the highway doing 100 mph. during af take over, my Ford F-250 6,4 Super Duty 2008, lost nearly all power. (now it is like driving my old hummer h1)
Engine and car runs/starts great, only 10 minutes uptil 60 mph. now.
My mechanic has given up. He checked following:
EGR = OK
HOSES = OK
ERROR CODES = NONE
INTER COOLER = OK
PARTICLE FILTER CLEAN = OK
TEST WITHOUT EXHAUST = NO DIFFERENCE
FLUIDS = OK
Hopefully something I can fix with my hammer. The car has 85.000 miles on the clock.
Ford - Explorer :: 2003 - Intermittent Power Loss - Sudden Bog Down And Inability To Travel Faster Than 20 - 25 MPH
2003 Explorer Sport, 4.0 L, 84K miles. Car just fell out of extended warranty and has been serviced exclusively by the dealer.
While driving, I experienced a sudden bog down and inability to travel faster than 20 - 25 MPH. The more pedal you give, the less power. In neutral, free revs will not go above 3000 RPM at full pedal and will rise and fall between 2000 - 3000 RPM. The next day all is normal again. This happened twice now and I am not sure why. No CEL, no stored codes.
Plenty of pressure (felt by hand only) out the tail pipe except when fluctuating during free revs. There doesn't appear to be any vacuum leaks. What I can check to correct this? Could it be bad fuel or water in fuel?
Golf/GTI VI :: Sudden Power Loss With EPC Light Came On
I just had my '12 GTI's 40,000 mile service done about 2 weeks ago. I put in a K&N air filter the day after the service. The only thing I noticed about the car after service was that I could smell coolant, they either spilled some or its burping some cause it was filled past the max fill line. Outside of that everything was copacetic until yesterday morning.
On my way to the gym with cruise control on ~74 mph on the highway I had sudden power loss, EPC light came on and power returned although felt reduced. When I left the gym it was off and I made it about a mile when under acceleration it hit at about 3k rpm, again sudden power loss and EPC light, power returned reduced. Drove about 5 miles to work and did a little googling with a million results.
When I left work to go home I made it about ten minutes into my drive before it happened. This time the CEL came on. I was able to drive home and back to work again this morning but I keep having power shutters followed by the EPC. I haven't had much time to dig into anything but I checked the connection of the coils and the intake connections with a flashlight at 4:30 this morning. Thinking it might be the MAF only because I recently installed the K&N and have read the oil can kill MAF's and I might stop to get a can of cleaner on my way home to try that route.
IF that doesn't work maybe I can get it on a Vag Com in the next couple days to get it sorted out.
Passat (B5) :: Oil Seems Overfilled And Sudden Loss Of Power
I have VW99 Passat 1.8L Turbo, automatic with 170K on it.
My car shop changed engine oil yesterday with 4 QTS of Mobile 5W40. Now, when I check my dipstick today, on level surface, the oil level is way too high on dipstick kink [the cross-hatched mark]. I run the engine, shut it off, and let it set for 3 min, but still the level is too high above the Mark. It wets the dipstick almost till the top of its Head.It was reading High when I first checked it, this morning, before starting my car.
It seems the oil is 'overfilled' or showing over filled; and the engine is about to throw it out from "filler cap" where Dipstick goes in the engine. I saw him using 4 cans 1 QTS oil, which I bought, into my car. They did change the "oil filter" at the same time?
Now, my car looses power while driving. When I accelerated from a stop/light, car slows down or limps. The car suffered a sudden loss of power.It runs awful for about a mile but smoothed out after acceleration.It feels like the car is running out of gas for a few seconds, then all of a sudden it kicks in. The car still drives ok though - No error messages/warnings on dash,CEL, no smoke, no hissing. I actually don't see engine oil thrown out or leaking though.
I don't know if the shop drained the "intercooler" while changing the oil, also I know nothing about its importance to my power loss issue. The net search manual/states "The engine oil, above the level, can be drawn into the crankcase ventilation system, and enter the atmosphere via the exhaust system". But it does says about damaging the engine/car.
Should I be worried about the damage to the engine?
