So far I have only experienced this once (today). I was on the freeway which ends and becomes a State Route. When I stopped for a traffic light the idle became rough. I put the car in neutral and gave it a little gas and it seemed fine. It has not done that again at this time. No CEL or anything came on. What do you think?
View 6 RepliesI have a 2001 Mazda Tribute with 150,000 miles that is meticulously maintained. This past winter (as far as winter goes in San Diego) the engine would run rough and the rpm's would drop close to stalling when stopping at a light for the first 2 or 3 miles. After that the engine has warmed and there is no problem. Could this be the intake gaskets needing replacement. This only happens on a cool or damp, rainly morning.
View 6 RepliesWhen exiting off the freeway and stopping at the light, my car felt as though it was bucking and idling very rough. I put the car in Neutral and it subsided a bit but the lit gauges were pulsing with the idle. It felt as though the car was going to die. I put the car back into Drive and it drove fine. I pulled over and shut the car off. There were no warnings or any other indicator lights on during this time. After shutting the car off and leaving it for a couple mins, I started it back up and the engine light was now on steadily. The rough/bucking idle was present as well. I ended up driving the car to the dealer where it is now being diagnosed and I haven't heard back.

After looking around online found out it could be a variety of reasons... gonna change spark plugs tomorrow hoping that's the problem... next cheapest fix would be the ignition coils... I'm just hoping its not internal, like piston or rings.
It's a 2007 Passat Wolfsburg 2.0T.... just went over the 53k mark.
The 2001 Passat 1.8lT has an engine warning light on and feels like it is running on less than all four cylinders.( very rough idle) This is the first time we have seen this particular warning light and the manual suggests that it has a problem with the catalytic convertor.( 170K miles on the car) The car had no symptoms until the light came on today and the car was serviced last week. ( oil change and new tires) It seems that every time I take the car in for service something goes haywire shortly afterward.
View 6 RepliesI started noticing a strange idle when stopping or sitting at a red light. Upon stopping the car idles at around 600, then all of a sudden it jumps to around 1000-1100, and sits there as if I was giving it gas. As I drive off the car drives fine, once I stop again, the same thing repeats. This happen to me 2-3 times already within the past month, I mostly drive on the highway, so that might be a reason I don't notice it often.
View 5 RepliesWifes car began to idle very rough and check engine light began to blink and beep, I took it to the mechanic today and he informed me that my control module was no good and it was a $400 dollar piece. I said go ahead get it done, cuz she needs the car and i couldn't afford to not have it done immediately. Question I have is does this small-ass piece really go for that much on average and what control module is it?
View 4 RepliesI just got a 2000 Passat 1.8T with a bad motor.
Symptoms include: rough idle, oil leakage, coolant light comes on after running for about 2-3 min., I checked the coolant res. and it has what I suspect is oil in it. I know that the PO ran cheep oil and oil filters the last 2 oil changes and this has caused the famous cannibalization of the engine but what I need to know is would this feed oil into the the coolant over flow tank? There also seems to be some oil/coolant seeping from the upper left.
The car only has about 90k on it and most of those are highway miles, other than cheep oil, the car has been very well taken care of.
Today on the way to work at a red light I'm stopped light turns green I try and go and no power in fact when I hit the gas my rpms go lower first thing I think is I fried the clutch but it idles fine an when I hit the gas rpms go down and the at wants to bog out. Then after I get it towed home I try and crank it over it doesn't start. My thinking then is fuel. So I go to check the fuses everything is fine when I try and crank the car to start it you can hear the fuel pump kick on and then when I go to turn it over I only have crank so could it be the fuel line is clogged? I thought that if it was an injector it would start and just smoke bad. It's a 1.8t Aeb engine and yes I change my oil every 3 k miles and do all the work myself.
View 7 RepliesSo I have 69,500 miles on my car. I leave it parked on a small hill for 3 days and when I turn it on after 3 days of sitting it sounds like it is going to stall and the check engine light blinks. I roll it to the bottom of the hill and turn it on and the light doesn't blink but just stays on. On top of this, randomly but always after stopping when driving i smell a really strong burning oil smell. The smell is so bad i have to open the windows.
I don't think it has anything to do with the CEL but it has been happening for some time. It only smells after you have been driving (mostly Highway) and then stop. It wont happened if your in traffic or driving around town, you have to be on the highway then get off and stop and you smell it. It can happen once a month or twice a week, it is completely random.
It happens in the morning or on cold starts. The car has a rough idle and the throttle response is terrible. Its very sensitive and jerky. Could this be bad spark plugs? Its a 2006 2.0T and its had all the maintenance done.
View 5 RepliesI have a B5 99.5 AEB and having rough idling. Started the car in the morning seem fine. Later that evening started up again in a warm up idle and then the car shut off. Tried starting up again but took couple of minutes. Pumped the gas piddle started up but looking at the idle gauge needle was bouncing around. I don't think i have an vacuum leak.
View 2 RepliesI got an 800rpm rough idle, no serious lack of power, every time after filling up w/ gas she starts slowly (bout 3 secs) and then tries to die. she catches herself and revs from 400-1200 for about a minute, then drives away fine. Getting:

16825 - P0441 Evap ECS : Incorrect flow

Also have: 01039 - Coolant temp sensor(g2) : open or short to plus? (intermittent)
Doubt the last has anything to do with BIG problem, but my temp sensor on ly gets off 0 when i am moving and using A/C...is this going to cause issue now/later/ever?
I drove home Saturday morning from work with no issues. Car sat until Monday night and as soon as I had to stop at a light it was idling very rough where the rpms were jumping 3-400 up and down. I make it to work and on the way home I experienced the same idling issue along with some misfiring. I scanned and came up with the following codes. I have no CEL. I had my APR flash, Forge Intake, Turbo back exhaust all installed 2 and a half years ago. I have owned the car for four years never having replaced the DV or PCV. 87,000 miles.

My 1.8t is very rough at idle when cold, smooths out when over 1000 rpm and when at normal operating temperature. Code reader says 171 and misfires.
View 6 Replies2000 Ford ZX2 2.0 ....I've got approx. 79,350 miles on this car. I'm the original owner. The "Service Engine Soon" light came on. I took the the car to an Advanced Auto Parts store, they hooked up their handheld computer to the car and told me "it might be an oxygen sensor or poor fuel octane", he suggested adding an octane booster and see if the light stays off. I did that,but two days later it came back on, the idle seems a little ruff when stopped at a light.
View 5 RepliesMy car started a rough idle last night.... Pull to stop light, in gear, a/c on #1 and car shudders and acts like it's going to stall..... Went away as I drove a round a bit.....back this a.m. (after the warm up program ran) drove it a bit and was sporadic.....and even went away...then came back.....
Its worse when car is at stop and in 'D'.....little better with a/c off and/or in neutral......it finally threw the CEL today....... I had the fuel pump recall done about a month or two ago, car has 36k+ on it...... Anything I should have the service dept look for aside from what the fault codes might read?
[URL] .....
Idles ok in park and neutral. Gets worse while in gear. Car has high miles around 160.000. Fuel injection flush? Fuel Filter? Vacuum leak, and where to look first? No check engine light, no misfire codes just a rough idle when in gear.
View 3 RepliesI've been having a curious issue with the engine in the Passat. When I put gas in the car, it generally is hard to start and stalls. This happens once or twice, and then the car runs great. Sometimes the check engine light will come on, but I haven't been able to read the codes. The mechanic said that the car was driveable. I am curious for potential causes and solutions?
View 4 Replies2004 1.8T, 44,XXX miles, Tip. So I left work today. As I was pulling into a turn lane, very slowly, and coming to a very gradual stop (maybe 10 MPH) the car felt very slightly rough. it wasnt even very noticible, but seeing as I notice every little thing, I picked up on it. It felt like the road was maybe a bit bumpy, but I wasnt sure. The Tachometer was at maybe 800-900 RPM, not really out of the ordinary, but something seemed odd.
So, just as soon as I thought "Well, at least the CEL isn't on", the CEL comes on, blinks 3 or 4 times and goes out. Other than what seemed to be a slight "roughness" for a few seconds, the car felt and ran as good as ever. CEL stayed out. I came home, then went to Autozone to see if i could get it scanned, but they were totally useless.
So - if the CEL went out, would a code still be stored? I know blinking is bad, but it went out after a few blinks. It didnt even stay solid, just went out. There was no message on the display screen either (no "Stop Car" or "Emissions Workshop" etc) First time this has happened. I read on PW that it could be the ICM. I'm hoping it's just a random anomaly.
B5 passat. Recently she took her car to the shop bc her cel was on. turned out her turbo was blown so she got it replaced with a brand new one along with the oil pump. about 3 days later the check engine light comes back on..idle is very rough and it feels like its misfiring.
First thing i did was check the coilpacks bc it was why my audi would always misfire but it didn't work. So she took it back to the shop and they said that her ecm is dying. Ive never heard of that happening.
The codes that came up from the CEL the second time were p0171, p0172, p0173, p0303
