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)

Prius (2004-09) :: Sudden Loss Of Traction Power And Engine Races

I have a Prius 2005 with an Engineer 4kwh kit installed [v4 bms]. Lately, I have experienced several instances where the Prius suddenly looses much of it's traction power and the engine races, and the red triangle and engine service lights go on at the dashboard. This happens with the kit turned on, and often after a few kit on/off cycles to get more ev mode. The Prius battery is sometimes low, sometimes not, when this happens. Not sure if it also occurs with the kit off.

The Prius seems to retain some traction power up-down by the throttle pedal, but most power goes missing. On the other hand the engine races and does not seem to power the wheels or vary by throttle. When I pull off the road using brakes normally, and turn off the car/engine and restart [kit now off], the car seems to reset and can resume driving normally, but the error code lights [triangle-engine] lights stay on.

Prius (2004-09) :: Sudden Power Loss And Red Triangle Came On / Code P0121

So I replaced my battery about 20k miles ago, so I know that's fine. I always throw a P0420, but I'm told that's fine too. So I was driving, and I lose power suddenly. The red triangle comes on, and I plug my scangauge II in, which tells me it's P0121, or the throttle body sensor. I reset the codes to make it home - my battery DID charge just fine on the way home, making it up to a 63.5 state of charge. Now when I start it, and press the gas, it tends to rev up, rev down, and repeat. I haven't gotten the red triangle again yet but I also haven't driven it since then.

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?

Prius (Gen 2) :: Battery Didn't Charge At High Altitude

I recently took a trip up .and I noticed that driving up long inclines my battery just drained to practically nothing.

When I got to level terrain it'd charge but to not to full level. and for my entire trip it didn't ever really charge much. However once I got down to lower altitudes and drove to my home It charged right up and has retained its charge.

Prius (Gen 2) :: Power Loss And Low Battery - Cannot Go Faster Than 50 Mph

I have an 07 Prius with 90Kmi (bought new) which now loses power while climbing sections of mtn passes. Battery meter shows 1 purple bar and cannot go faster than 50mph. No warning lights or fault codes. Never an issue before & intermittently happens around town. 4 dealer visits and extended tests with TMC field techs have allowed them to duplicate the problem at least twice. Interestingly Toyota doesn't know what or how to fix this.

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?

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 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?

Golf IV R32 :: Sudden Loss Of Power While In Cruise Control

Earlier this evening on the highway while in cruise control I had a strange issue. Going up a slight incline all of the sudden I lost power, my ESP and EPC lights came on, and the engine was running very strange.

It wasn't stuttering but was louder and vibrating a whole lot more than normal. I pulled over and shut the car off for a couple mins, started it up, everything was normal and continued. About an hour later the same thing happened and when I started up the car again the check engine light was on.

I had my room mate scan it when I got back and it came up with ECM and PCM processor errors. Not sure what kind of problems this would be. All the searches on cruise control didn't turn up anything like this. What the problem would be? The cars a turbo'd r32.

Dodge - Dynasty :: 1992 - Sudden Power Loss?

This has happened to me three times now. The first time was at a stop sign, the second going 70mph on the highway, and the third time at a stop sign. I will be driving and then all of a sudden the engine loses power. The more I push on the gas, the more the engine wants to die. If the engine stays running after I pull over, it idles very rough, and still if I press the gas, it wants to die. This seems to only happen after driving long distances for maybe an hour or so.

When this happens, if I let the car sit for about an hour, it will start up just fine, idle smooth, and drive normally. This is a 1992 Dodge Dynasty with the 3.3L V6, Fuel Injected engine. The car only has 78,000 miles on it and is in excellent condition. It's such a nice car that I would like to figure out what's going on with the engine because I would like to drive it for a lot longer. So far I have replaced the ignition coil pack, the oxygen sensor, map sensor, fuel filter, and spark plugs an wires.

Prius C :: Does The Battery Show Full Charge?

I've had my C a week and a half and it is doing great, but I wonder if the system is ok. It has never shown the battery at 100%. My Civic would charge all the way quite often.

Volvo :: 94 850 Turbo - Sudden Loss Of Power When Put The Pedal To The Floor

Took my 850 Turbo out on the freeway today, and when I put the pedal to the floor on the onramp there was a very disconcerting loss of power just as the turbo was really kicking in. No issue under mild to medium boost, but when pushed hard there is a short loss of power/hesitation, almost like a backfire, then boosts again, then the same power loss until I back off on the gas. Cannot get full boost without this happening.

Phaeton :: Sudden Loss Of Power When Driving At Around 140KM/H On Highway

I've been driving my V10 for 3 years now without a problem. The other day, while I was on the Highway in Italy driving at around 140KM/H, I suddenly had a loss of power. I could continue to drive the car, but I had no more tork... I stopped at the next gas station, turn the engine off, turned it on again, and the car drove normally again as before. About 200KM later the same happened again...

I went to check with the dealer - he hooked up the car to the computer - and told me that they had to change both turbos... What I find weird is that when I turn the car off and on again it works again. If the turbos would be defective, they wouldn't work again just by turning the car on and off. I think that it is more a problem with the turbo controller and if that's the case why change both turbo.
