Elantra XD (2001-06) :: 2005 - Loss Of Power On Acceleration / RPMs Surge Up Very Slowly
So my 2005 elantra 2.0 CVVT has 189k on it 1 owner.
I got a check engine light one day and i read the code. Came out to be 02 sensor code bank 1. So i order a denso o2 sensor and replace the part.
I drive the car for about 400 miles to reset monitors and get a check engine light. P0420 cat code. At this point the car drives with normal power and pickup.
1000 miles later my car has lost power. It doesn't have any get up or power when driving normally. I take the car to my local shop and they recommend replacing front cat. I replace front cat, same issue.
At this point i'm not sure if it is a transmission problem or maybe my 2nd cat or something else?
On the freeway if I put my pedal to the ground the rpms surge up very very slowly,
Also seems like the car doesn't shift till around 4k rpms, seems like previously it shifted sooner.
Prius (2001-03) :: 2002 - Sudden Loss Of Power While Driving Followed By Alert
I've been having this problem where as i'm driving (mostly highway) all of a sudden I get the feeling like i've let go of the gas pedal but I haven't. The mpg meter goes from about 40 to 100 as if its on straight battery power and I have to really press the pedal down to get any decent acceleration. Once in awhile i'll get the big orange triangle warning and the little pic of an exclamation point in an outline of a car. But after a day it may go away.
One time it didn't and I brought it in. I spent 80 bucks for them to find nothing wrong and say the alert had something to do with an oxygen sensor (its was awhile ago, i dont quite remember exactly)
Santa FE SM (2001-06) :: 2003 2.7 - Sudden Loss Of Power At Highway Speed
On my '03 Santa Fe 2.7, this has happened twice, with 500 or so uneventful miles in between. At highway speed, it just all of a sudden loses power and will only go about 50 mph with accelerator to the floor. When you stop & put in neutral, it only revs to about 3000 rpm, with pedal to the floor -yet idles fine. Then when you shut it down, wait a few minutes & start it back up, it's fine. Is this a fuel problem or what?
View 6 RepliesGolf/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.
Santa FE SM (2001-06) :: Sudden Clunk Then Power Loss And Car Started Shuddering - Throttle Body Or MAF?
I was driving down the road and the car was driving great. all of the sudden I heard a clunk and the car lost power and started shuddering. I made it home and cut the car off. When I start it now, the car runs rough and stalls out. I can't get it to a place to check the codes so I am trying to self diagnose. I was thinking it might be the MAF so I took it out and cleaned it well. there is still no change in the way the car runs. it seems like the fuel isn't getting to the engine as I put my foot on the gas pedal it stalls out. I'm not too excited about buying a throttle body if it's the MAF. It could possibly be something else.

I have passat 2007 2.0T , about 98000km. A few months ago, my vehicle randomly has hiccup with EPC light when I put on the pedal. Each times i put on the pedal my vehicle hiccups and EPC light on and all goes away when i put off my foot from the pedal. It happened randomly, so i went to vw dealership twice. They keep saying they could not find any problem. Coz as i said it happens randomly. I paid diagnostic fee but still the problem remains.
Unfortunately today i had the same issue hiccup like crazy with epc and engine lights. Also on the highway my baby 2 years old was with me when i drove, my vehicle lost power all the sudden, all most i involved an accident with following vehicle. I started the engine, vehicle moves but with the problem. I feel wheels do not spin properly or transmission randomly. What the problem is?
Ford Super Duty (1999-2016) :: 2001 F250 V10 - Sudden Power Loss And Dies Randomly
I have a 2001 f250 super duty extended cab with the v10. Over the past week it has been running fine and it will all of a sudden lose power and dies. I've been able to start it back up once right away and a few times it started up after a few hours of messing with it.
So, after the truck dies it will crank and crank but will not start. We have checked fuel pressure and nothing. Then we applied direct current to the fuel pump and it turns on. Then we applied direct current to the fuel pump slot in the fuse box and got a fuel pressure reading of 40 psi. But when we crank we have no pressure.
When we apply direct current to the fuel pump slot in the fuse box the truck will only crank and not start.
Ford Super Duty (1999-2016) :: 2001 V10 - Sudden Power Loss After Sitting In Long Traffic Jam
My excursion suddenly lost power after sitting in a long traffic jam. I have a scan gauge II set up and didn't see any signs of over heating however when I went to accelerate back up to highway speed my motor revved up to 3000 rpm and just lost power I ended creeping on the side of the road at about 15 mph and barely maintaining that. The motor was not willing to revv up. I reached a spot to pull over and shut it down for about 15 minutes and started back up and drove off with no noticable issues. I have 211,000 miles on this motor and I am going to change my coil packs, I think they have been there since the truck was sold new....I changed four of them to address a miss and have six left, I will also be changing my fuel filter. We are about to pull our camper across country....about 1400 miles..

2001 Hyundai Elantra GLS ... I don't know what is going on with my car. When I start it, put it in gear and try to pull out, it feels like there is a loss of power. A few seconds later, the power returns . I can push my foot down, and the engine doesn't rev, but then it's like all of a sudden the engine realizes I have my foot down and takes off.
View 3 RepliesElantra XD (2001-06) :: Power Loss When Accelerating
Mine is 2006 with 130k miles. Just replaced fuel filter, air filter, cleaned air flow sensor and cleaned the injectors. The car still feels slow and it seems to eat more fuel than before. The spark plugs and the wires seems to be ok. No warning or error on dash is displayed.
When push the accelerator it takes a while to respond starting from stop position, and when the car is moving and try go faster it feels like lazy so I have remove the feet of the pedal and push it again so it respond quickly.
Elantra XD (2001-06) :: 2003 - Loss Of Power While Driving
My friend has a 2003 4 cyl auto Elantra. His problem is strange, while driving the car is normal for maybe 1 - 5 hours then out of nowhere the car will only go 15-35mph and no matter how much you press the gas pedal the car will not accelerate. It is a bogged down loss of power not like it's just stuck in a low gear. This has been happening for a while now but now it's happening all the time and very frequently. Before he could shut the car off for 5 minutes and it would be ok for another 1-5 hours. It got so bad that he can only go 20 miles before it happens and now it seems the longer he lets the car sit off the longer he can go before the problem happens. Hyundai has had the car for a week and still have no clue what the problem is but it has not happened while they have had it. There is no CEL or any stored codes which is making this really hard.
View 1 RepliesElantra XD (2001-06) :: Loss Of Power And Speed At 100km/h - No CEL
Firstly, I've had an extensive look through the forum for existing threads dealing with this issue and have found a couple that seem to match... however I'm not entirely sure because noted that they had the car CEL come on... My wife's car doesn't. These threads dealt with gear shift flare, range selector switch faults, ECM reprogram - RPM flatspot... All except the latter noted that the CEL light came on...
Our problem - Loss of power and speed at 100km/h (auto trans)
In fourth gear (auto) traveling at 100km/h, RPM at this stage has settled to around 2100-2300. Then kicks down into 3rd (I'm assuming) with RPM just above 3000, and with little acceleration slowly build up to 100km/h and then start losing.
Elantra XD (2001-06) :: Stalling / Power Loss And Car Would Jump Gears
Almost two weeks ago, I began to have a problem with my car. (2001 Elantra) At times it acted like it was about to stall as I was driving up the smallest incline. Once I got up the incline, my car would jump gears. (second to third, so on)...
The car was taken to Advanced Auto where I received codes about the catalytic converter and the output sensor. I've known about the converter since I bought the car last year and the sensor was replaced. But I am still having problems with the car. My friend is literally having to drive it like it was a stick.
We fear it might be the transmission as I you can go in reverse with no problem. What it could be instead of the transmission?
Elantra XD (2001-06) :: 2003 GLS - Power Loss / Car Goes Into Starvation Mode And Won't Accelerate
This car has turned into a bad dream. When it first starts in runs well for a mile or so until it warms all the way up. Then it goes into starvation mode and won't accelerate. Maybe a cough or two then it runs fine for 10 or so seconds. And goes back to stumbling. Most times I have to pull over out of traffic and wait for it to so call catch again.
I have changed plugs, wires, coil rack & fuel pump module. Because someone else looked at it before I did, they erased stored codes. I have pulled 2 codes on 2 different occasions. The first was P0134 the second was P1166. Other times no codes were stored. I did notice that if I shut off ignition & restart it runs great for 10 or 15 seconds.
Elantra XD (2001-06) :: Sputters While Idling And Power Loss If Try To Accelerate Hard
My 2004 Elantra occasionally won't start. When I hold the ignition on Start, the radio loses power (but the dashboard doesn't) and nothing else happens. Sometimes, tapping the gas pedal will suddenly cause the car to start. Once, I had to stomp the pedal to the floor before it would work.
I just replaced the battery (and positive cable end since it was corroded in place) and recently replaced the spark plugs (which were badly burnt). There is a check engine code for "catalyst underperforming" which seems unrelated.
I suspect my car has fuel delivery problems. It occasionally sputters while idling and often has power loss while driving if I try to accelerate hard. It seems to have trouble shifting into 4th gear from 3rd or 5th, but that may be another issue entirely.
What I should check to diagnose this, or replace to resolve it?
Elantra XD (2001-06) :: 2003 - Stalling / Loss Of Power When Idle And Press The Gas To Go
I got a problem with my 03 elantra, recently the car had a problem of stalling. I replaced the crank shaft sensor and that fix the problem, but the car always when idle and then press the gas to go feels like it has no power at all then all the sudden all power kicks in it only does that for a second when i press the gas. What I did was to replace the fuel filter that actually was extremely dirty,but no change i guess it could be the fuel pressure regulator.
View 10 RepliesFord 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?

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?
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?
