Golf/GTI VII :: Stumbling And Jerking When At Idle
Is this a sign of a turbo going out or ? my GTI currently has 1700 miles on it and not all the time, but in the past 1700 miles the car has stumbled or jerked around a bit when at idle, i.e. the rpm's don't do anything but it seems like it's misfiring or something a few times then generally clears out. Same when driving sometimes, cruising along and it seems to misfire or stumble around but it clears up as well. Haven't noticed anything else weird but it's annoying and worrisome.

Just stopped by the dealer to check on some parts, went to start the car, and this happened. Also smells rich as hell. Did I just drop the ECU code?

2010 Prius engine start stumble - YouTube
Started out with no code, then check engine light started coming on. P0301, misfire cylinder #1. Sparkplugs were replaced, and coil pack for #1 switched with known good one. EGR tube also cleaned of carbon.
Stumbling/roughness has been getting worse, about an inch of coolant used per week of driving. No oil in the coolant, and no coolant in the oil (no milkshake or anything like that).
Dirty fuel injectors were suspected, but no improvement after using Techron. Finally, a boroscope was used to inspect the cylinders through the sparkplug holes, and a very slow leak was found in cylinder #1. Since liquid cannot be compressed, during the compression cycle significant misfiring occurs.
Golf IV R32 :: Misfires In Low RPM Range / Stumbling And Just Not Firing On All Cylinders
Ok so I'm having weird issues with my big turbo R. I thought I was having misfires in low rpm range. Car was stumbling and just not firing on all cylinders ( just an expression but that's what it felt like) realized it was because of the esp. Ok no the main issue. Vacuum was sitting around 14hg. When I come up to a light or stop sign or just put in neutral while moving it revs it self ad vacuum will go to almost 0hg until I come to a full stop.
The rev is not a big rev only like 100-150 rpm increase. Also the throttle response is not there if I go to rev match down shift. Here's the weird part. If I unplug the Maf it runs super smooth 19-20hg vacuum amazing throttle response clutch chatter almost goes away. There are no cel with or without the Maf plugged in I have logs for both...
Golf IV R32 :: Running Rough And Stumbling A Bit - Code P0103
124k, original owner, no mods. Car was running rough and stumbling a bit. A bunch of codes came up. I replaced coils because I had them, spark plugs look good. One code came back p0103. I cleaned the throttle butterfly and replaced the maf sensor. Still same problem.
When I first start it cold it idles high but stays running , once it warms a little the idle drops and then it won't stay running. Then the traction control light comes on and then the cel. I checked for a vacuum leak but came up with nothing.
Golf IV / Jetta IV :: 2001 GTI Engine Stumbling - Car Barely Accelerates
The issue: Check engine light on. Codes pulled, and he's getting O2 sensor codes (aftermarket exhaust has caused that since he bought the car) and 17705 Pressure Drop Between Turbo and Throttle Valve. The car barely accelerates, and you can hear the turbo spooling, and the engine has small surges. I had VCDS going and went for a drive and noticed his N75 Valve duty cycle was stuck at 5.1% no matter what throttle position he was in. So we're going to the wreckers this afternoon and will pull an N75 valve? The DV is stock and appears to be in good condition, but if changing the N75 doesn't work then that's the next spot I'll look.

View 24 RepliesGolf/GTI VI :: 2010 - Second Gear Has Loud Whining Noise
I have a new GTI which is awesome, but second gear has a very loud whining noise. Very easy to reproduce: in second gear rev it up to 3000 rpm and let go of the gas. This happens only in second gear. Under a moderate acceleration or while engine braking. Should I be worried, should i have it checked? Is this normal? It is a 6 speed manual gear box.
View 24 RepliesGolf IV / Jetta IV :: Very Hard To Get A Smooth Shift From Gear To Gear
Background facts:
Tranny swapped from my 4 speed auto to a 1.8t o2j 5spd
13lb. Light flywheel
Powerflex dogbone mounts
Peloquin LSD
The problem: Very hard to get a smooth shift from gear to gear. Trust me, I know how to drive, but I can always feel the car shifting into a different gear if you know what I'm saying. On my friend's bone stock Jetta, I just let the clutch out without gas in between shifts and you don't feel a thing.
On my car, you feel EVERYTHING. People have told me the light flywheel will make the ride more uncomfortable in many ways, especially since the RPMs drop much quicker in between shifts than stock.
Sierra :: 1991 GMC Engine Has Been Stumbling
I have a 1991 gmc 1/2 ton with 200K on it. Its a 350 engine. The engine has been stumbling for a long time. I've tried many things ...new fuel pump and filter...complete tune up.....checked all vacuum lines..replaced a couple lines...EGR valve.....changed head gasket and intake gasket. Checked the warm up flap inside the air cleaner. I am now very very frustrated.
This stumbling happens often but intermittent also....sometimes worse than other times like the truck is about to stall. The truck seems like its being held back like a loss of power. The truck will begin to stumble so i will pull over and rev it up and it seems to clear itself for a short while then right back to stumbling.
Upon warmup in the morning she seems to run fine until hot. No codes being thrown ...service engine light NOT on. Even while at a stop i will hold the throttle part way and revs at different rpms. I am now at a loss and feel defeated.
Passat (B5) :: 2002 1.8T Stumbling At Idle
Within the last week, while sitting a stop light, the car will very briefly (2 or 3 seconds) shudder and stumble. The RPMs drop a couple of hundred +/- and then it's fine. I have no other symptoms - no power loss, or reduced mileage. I've not experienced this before and it's happened three or four times recently. Is this indicative of an impending failure of some component?

View 8 RepliesSubaru - Forester :: Stumbling At Around 2500 Rpm
I have an '06 Forester XT 2.5 turbo that has, what I can only describe as a stumble around 2500 rpm. The car's maintenance is always up-to-date, and never has anything under 91 octane run in it.This started out when you had the cruise set and now does it all the time whether or not the cruise is used. I've had it to 2 shops including a Subaru dealer that had it for a month and couldn't find the issue. We've been through injectors, coils, maf sensor, etc. to no avail. The trouble code that we're given is a misfire in cylinder 1. We discovered, while trying to find the issue, that there was only 30psi in that #1 cylinder and the valve guides were the issue. So the motor was pulled, heads planed, etc. and new guides installed. Also, put in a new timing belt, and so on, that is usually done when the motor is out.They have done a leak down test and compression tests as well. This is my wife's car and she absolutely love it, so I need to get this figured out.
View 2 RepliesPassat (B5) :: Cranking And Stumbling But Won't Fire Up
I just bought this car... today... ran great until I got a few exits from my apartment (I think the car knew I had my hopes up for successfully making it home) and all of a sudden the car shut down. There was no smoking, shuddering, or weird scents of any kind. Had my girlfriend following me and she said she didn't see or smell anything... the oil level is good, pretty clean... coolant is clean and pink... timing belt was just done about 5k ago... but she cranks and stumbles a little but that's about it. Battery died from repetitive attempts at starting and now I think that old girl needs to be replaced... but does this sound like a crank position sensor issue like I'm guessing? or possibly cam position sensor? Also might add that the dipstick and oil cap hole had a little smoke coming out of it when I pulled it to check the oil situation... B5 1.8T wagon

My 3.5 intrigue seems to stumble while driving it. It feels as it the engine is stumbling or loses power for less than a second and it will do this a few times in a row and will be fine for awhile and then repeat itself.
This can happen while cruising, slow acceleration or at a stop light. I don't really notice it under harder acceleration. When it does happen i do notice that the rpm's drop a very slight bit.
Volvo :: 1982 Turbo Wagon Hesitation And Stumbling When Hot
I'm a newbie who just took ownership of a 1982 turbo wagon. It's been sitting a while but started right up and ran well for about 20 miles until it began stumbling on acceleration.
The car starts easily and runs smoothly until it gets hot and then it suffers severe hesitation and stumbling. Occasionally it will stall but starts right up again. It has never failed to restart immediately.
On a cool day, it will run smoothly for thirty minutes or more before the problem begins. On a hot day, the problem begins in five minutes.
