Golf V R32 :: Rough Idle After Cold Startup

If my car's been sitting - say monday morning after sitting all weekend in the garage- it runs rough for a little while. Sometimes only for a few seconds, sometimes for a little while after the idle drops. The colder the car is, the longer and worse the condition. It feels like a cylinder isn't firing.

After a particularly cold and wet spell (I had the car outside) it ran so badly it threw a code for one of the cam position sensors and #4 misfire. I replaced both of the sensors. That worked a little.

Since I was due for 80k service and saw a misfire when damp, I replaced the ignition coils along with the spark plugs. That worked a little more. But, it still does it. What else could it be if not ignition? Sticky valve? something else?

Golf/GTI VII :: Rough Idles And Stalls Out / Bank 1 And 4 Misfiring

My gti with 5k miles will be in the dealership 3weeks on Monday! No one has been able to diagnose the problem! I called VW corporate and they told me that the dealer was working with their tech support and engineers.

The problem is has really rough idle were it stalls out. Bank 1 and Bank 4 are misfiring. This is the part were they are stuck. Once they remove the oil cap the car runs perfect! It stops all misfires and idles perfect. They've ran smoke test, compression test, vacuum test. Replaced pcv, high flow fuel pump, intake manifold.

Golf IV / Jetta IV :: 2001 VW 1.8T - Rough Idle And Often Stalls Out When Press The Gas

I have a 01 vw bora 1.8t and recently I let it sit for one day and now it has trouble starting when it's cold and when it does start it has a very rough idle and often stalls out of you try and press the gas. Once it has warmed up she runs fine. My check engine light is on but I have no way to take her down to a shop to get the codes read. What is wrong with my car? One of my friends told me it could be a cool pack or a sensor.

Ford - Explorer :: 2002 - Either Stalls Or Starts - Runs Rough And Then Stalls With No CEL - Water In Fuel?

We've had two problems within the last week with our 2002 Sport Trac (4.0l SOHC engine w/167,xxx miles). They may be unrelated, but I suspect there's good change they are. Both incidents happened while my 16 yo daughter was driving, so there's only very limited info on what happens. Both times, when I get there, it starts and runs fine. There is no CEL.

The first time it apparently stalled as she neared her destination after driving only about 2-3 miles at 35 mph or less after a cold start. She was slowing to pull into a parking lot and reported the dash lit up with warning lights, no power steering assist and no power brakes and no power from the engine. When I arrived it started and ran normally. She had fulled up the day before after two days of heavy rain, so I suspected water in the gas. I drove it more than 200 miles within the next 24 hours under a variety of conditions and filled up at a different station. I experienced no problem what-so-ever, and didn't bother adding any dry gas.

Then 5 days later (still on my fill-up) when she tried starting it after sitting all day, she reported the engine started but ran rough before stalling and never idled normally.

Doesn't the fact there's no CEL eliminate a lot of the upstream part of the control system......like sensors and actuators? This leaves things like the downstream parts of the fuel and ignition systems. I.e. from the fuel tank / pump to the injectors and the downstream parts of the ignition system.

What are the possible culprits? Fuel pump, fuel pressure regulator, injectors, ignition module, spark plugs, and....... what else? (I'm not that familiar with what these engines have) And of the possibilities, what are the most likely causes.

Camry :: 1996 V6 Stalls At Startup

We have an older Camry (1996 V6) with 159K miles on it that we are going to use for my gf's daughter's first car. It sat unused for a while and her father is giving her the car. The issue is that when you initially start it you have to keep the foot on the gas or it will stall. It does a bit better when it warms up but it can still stall if you let off the gas quickly. The plug wires look quite new so I expect the plugs are new as well (will confirm with her dad). I pulled the throttle body and it doesn't seem to be very dirty but I will clean it anyway and change the air filter. What I did notice is when I pulled the vacuum line (I'm guessing that's what it is, I am not mechanic) it was split longitudinally through the clamp. I am going to replace the hose but am wondering if the throttle intake is fairly clean if this could be the cause of the rough idle. I've watched a video on-line that shows how to clean the throttle body.

The battery looks fairly new but I don't have my voltage meter to test it. I have cleaned all the connections because I have heard that a weak battery or bad connection can also affect the way the engine runs. This Camry doesn't have a voltage meter, only a dummy light. The light doesn't come on so I'm thinking we don't have a problem with not getting enough power to the computer.

Passat (B5) :: 2002 - At Startup Stalls / CEL Came On

I own a 2002 Passat 1.8T and have had a check engine light for the past month or so. I was finally able to get it to one of my local mechanics who specializes in german made cars. He showed me where one of my vacuum lines had split open, then proceeded to splice the line with a t-fitting and a new length of hose and then reset the check engine light.

Well, the engine light has stayed off, but now when I start the car, it almost stalls out right after startup, then proceeds to idle and run fine. The mechanic thinks that since the car was running for so long with that vacuum leak that the ECU needs to to "reset" itself to the different pressure.

Golf/GTI VI :: 2011 - Rough Idle And Stall

So this morning when I went to start my car for work, it wouldn't idle and was misfiring badly, also has a very loud noise coming from the valve cover. The car has under 40k miles on it and is CPO, so it'll be towing it to the dealership today to get check out. The car ran fine on friday when i parked it.

Here is a vagcom scan I did this morning also.

Tiguan :: 2012 2.0 TDi Misfire And Sputters Then Stalls On Startup

I have recently purchased a 2012 facelift Tiguan diesel and it has a running fault. When starting the engine, 50% of the time it starts fine, 50% of the time it starts with a "misfire" and sputters for a short while (5-6 seconds) then stalls. If you Rev it a bit while it is sputtering then it clears the sputter and doesn't stall. It doesn't matter if it's hot or cold. Once it's running fine then the misfire never returns until you shut off the engine and then try to restart. The start stop also fails to cut in and I'm wondering if this could be linked. It had a new battery and alternator fitted a few months ago but a non start stop battery was fitted. This has now been changed for the correct battery but both problems still persist.

Camry :: 2005 - At Startup RPMs Keeps On Dropping And Stalls?

I have '05 Camry v4. Everything was fine but three days ago I started to have issues. At first I tried starting the engine it would fire up with RPMs going to about 2000 as per usual start. Instead of going down to 800 as it usually does the RPMs just keep on dropping until car stalls. On the first day it started happening I would simply try to start the car again and it would start.

Progressively it would take me more tries to start the engine. It's always the same way (be it a cold start or a start after I've just drove for a while). First try - the engine starts and stalls right away and after that I have to keep on trying to start it for some time. So finally it wouldn't start at all. Starter cranks, battery fine, but the car simply would not start. Weird part about it, is that once the car starts it acts completely normal. No spikes in RPMs, no loss of power, nothing! At this point I just don't know what the hell it is.

Grand AM :: 1996 - Theft System Light Comes On And Then Car Stalls After Startup

When you start the car the theft system light comes on and then the car stalls. This has been a continuous problem for about two years. I can't find any pattern to when it does and does not start. Sometimes it will start again the next try, sometimes 30 minutes, sometimes I have it towed to the pontiac dealer after a week of not starting. Recently I have had the cluster sent out twice to check for problems, a new lock cylinder, and the bmc replaced. (about $1,150 total) This was done by a certified pontiac garage and the problem is still not fixed so I dropped it off again last night. Any suggestions? Also is there a point where I should get reimbursed for having parts replaced that were not broken? I have to believe that if the problem is still happening then there was nothing wrong with the lock cylinder or the bcm.

Accent MC (2006-11) :: Car Silently Stalls After Startup And Then Won't Start Back Up

I have a 07 accent coupe That is giving me a little bit of trouble. This morning when I started the car, it ran for about a minute and then quietly stalled. No hesitating or sputtering, just turned off as if I turned the ignition off.

So I tried to restart but it won't fire, i can crank it just fine and I have gas, so I'm not sure what could be the problem.

Sometimes though, when I fill up my gas tank. The car will splutter and try to stall for the first 30 seconds. I have to keep the throttle-up to keep it from stalling. But that only happens occasionally when I fill the gas tank.

Ford F-150 (2009-2014) :: 2010 - Misfire Right After Startup - Almost Stalls Out At Stops

My 2010 F-150 5.4 L has developed a misfire. I don't have the codes right now but can get them. Replaced all plugs and 3 of the 8 cops. Misfires right after startup but as it warms up tends to smooth out. When it is acting up it almost stalls out at stops. Where to next?

Prius (2010-12) :: Engine Rough And Loud At Startup

I have driven 25,xxx miles on my 2010 Prius. Three times during the last thousand miles I have experienced very loud and scary engine noises during start up. The car had sat for at least ten hours outside in 20-30 degree weather.

I took the car into the dealership for an oil change and my service advisor told me that Toyota was aware of the problem and the noise was not coming from the engine- but a device that mates the ICE with the electric engine. He told me that although it was a loud and dangerous sounding noise, it was not something that would harm my motor. I asked that the noise be logged into my service record.

Passat (B6) :: V6 Runs Rough For 1 - 2 Minutes At Startup When Cold

My V6 3.2l runs very rough for 1-2 minutes at startup when cold i.e. the first startup of the day, or after it has not been driven for several hours. Is this normal? I understand this might be something to do with the 'anti-knocking' feature. But I only use RON 98. Also I can here something like a tappet sticking when idle all the time. Is this normal, is it just a noisy engine design? The car has only done 1800kms.

Civic - Honda :: 2008 - Running Rough On Startup?

I have a 2008 Honda Civic with 65K miles. It's started idling rough and vibrating just on startup when it's been sitting overnight. This continues until I start driving up the road at which time it stops. I ran a fuel cleaner through it and changed the air filter, which was slightly dirty but not too bad. No effect. Then I took it to my Honda mechanic and he said there was nothing wrong with it.

Ford Aerostar :: 1992 - First Crank Rough Idle On Startup

1992, shory 3.0 130K MILES

On start up runs very rough, will stall if not power braked or revd a little on start up/out of the driveway.

VOLT METER STARTS GOING NUTS!!

After a mile/warm up,,, runs great. But sometimes even when its hot, it will still try to do the rough idle briefly after just a few minutes restart. Give it a few revs at that point and its good. And once in a blue moon it will do it randomly at a stop light,, out of the blue. Very rare
