Just checking in to see where you'd recommend to start looking for a rough idle issue. It seems to get worse once the car fully warms up. I took a vid, and although it may not seem horrible in the video, it sometimes causes throttle lag from a stop and causes the car to get close to stalling when falling from high RPM's. Take a look at the video .....
View 2 RepliesI have a pretty bad flex pipe leak on my 20th. Would this leak cause a very rough idle almost stalling when I come to a complete stop. The Idle fluctuates from almost stalling to 1000rpms.
View 1 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 RepliesHave a jazz blue chipped tuned with giac.. It does this random times.. When I come to a red light on idle the rpms go up and down just a bet but never stalls. The car vibrates and the engine shakes a bit. Engine is stable when car is on and off. Idk if its motor mounts or what?
View 10 Replies1995 Honda EX with 150,000 miles. Its been running rough ie rough idle, stalling at low rpms etc Additionally for awhile now when humidy reached north of 85% the car wont start. It cranks but rarely runs.
Took it to a mechanic last week for a tuneup. They replaced the Distributor cap, spark plug and wires and fuel filter. Car ran great for a day. Then progressively got worse. Was undriveable the other day stalling misfiring while at speed. Took it back today. They determined that it was still not getting spark and replaced the distributor. They did so, test drove it, declared it good and I came to pick it up. Paid the bill, walked out to the car and the damn thing would not start. Humidity was high.
Mechanic pulled a spark plug and put a tester in and didn't get a spark when cranking. He is assuming the distributor he just put in is bad. So they are keeping the car overnight to be fixed in the morning with a new distributor.
However I'm not convinced the dizzy is bad, I believe, as I've read that the Honda's ECU is probably bad and shorting out in the high humidity. Can a bad ECU would prevent spark?
I bought my gti about a month ago and every time I warm it up in the morning or any time it has been sitting over a long period of time the rpms sit at about 1300 until about a minute and it goes under 1k ... I am not to familiar with this issue.
View 14 RepliesSo I purchase this 20th couple day ago ( love it alot !!) but i noticed that the asr light stop working. When I press the asr switch the light comes up which i think its telling me that works. But its supposed to work when you go high rpm's right ? just wanna know since i am a totally newby in the 1.8t engine ...
View 11 RepliesI was driving yesterday going up a hill in lower gear... i think 3rd... and had the RPM's up sort of high, I heard a noise that sounded like if you stuck a stick into a fan...smoke also came out of the exhaust when pressing the gas.. smoke has come out before but I got my oil changed figured it might have just been burning off some oil.... I was thinking the catalytic converter??
View 2 RepliesSo my 20th runs completely fine until rain is involved.. Once it rains and I bring my rpms high or use my turbo it almost staples out and the gas doesn't work.. Also I notice it shoots out a puff of white smoke and my. Turbo doesn't spool at the way.. It basically tries and just does something like psh psh psh psh like second spools? Could water get in my. Turbo or something.
View 19 RepliesI have a 05 gli and when in idle the rpms go down really low then shoot back up. what could be the cause and how would i go about fixing this?
View 1 RepliesI have a 05 gli I just put a k04 turbo on. It runs on stock ecu but I have been told that's not the problem. When I start the car the rpm's spike to around 3 grand then slowly drop to normal idle rpm's when it gets under 1000 rpms the car starts to shake and idle hard. Idk what it is Cel is on and read misfires in 3 of 4 cylinders but checked plugs and everything they r fine. I'm thinking maybe vacuum leak or something along those lines.

I've gone to 3 mechanics now and no one can seem to figure out whats wrong with my car. Here's whats happening:
About 1 1/2 years ago I took my car to get an oil change at Jiffy Lube (Yeah never again). When I left, my car was idling funny... Silly me didn't take it right back and have them tell me what was wrong.. so I let it go, well about a month later it started idling even weirder. Basically it feels like my car is shaking when it gets under 1000 RPM and I notice my RPM dial start falling and bouncing back, acting like its going to stall, but never does. I notice a loss of power when this is happening (on speed up and just accelerating in general). All of this is random, I can't seem to put a pattern to it as to when it happens. One day I'll start it up and everything is perfect... Then I'll shut it off and restart it later, and it starts vibrating and puttering again... No signals as to if its hot/cold or wet/dry, no environmental variables seem to cause it to happen anymore than others. And there is no check engine light on, everything "looks" normal.
What I've had done to it so far is:
Air filter changed / reseated
3 oil changes (keep getting told it will work)
Throttle cleaned
Computer reset for idle sensor data rebuilding
Now I'm told that I need new engine mounts, and that could be the reason for the vibration. I'm thinking that the vibration caused the mounts to wear out, more so than the mounts being the cause. Mainly because I don't see how bad mounts could cause loss in power/bad idling.
What could be wrong?!? Really bugging me and don't want to keep throwing money at it for phantom solutions. Seems like mechanics I go to can't figure it out unless there is a check engine light on with some diagnosis code to tell them exactly whats wrong.
The car will start up fine, run for 10 - 20 min and stall. I will try and restart it but i takes atleast 7 or 8 sec of the car just turning over before it slowly fires up. Which results in a high idle 1200-1400 rpm and the car stalling another 5 min later.
Ive fixed my o2 sensor the wire was cut, replaced the fuel filter, and got a eurojet lower pcv hose for the vacuum leak i found.
So I was warming up my car after work tonight, and it was idling really rough right above 1RPMS and i heard a lil knocking noise from the engine what could have caused this? I was parked on a slight hill but i doubt that has something to do with it.
Also my buddy told me a way to see if my clutch was going out, is to try and kill the car while in gear, so i tried 1st time it shook really really bad but didn't die. So I tried again and it seemed like it was trying to catch its self and then shook bad again and then died. I did this in 1st gear just letting off the clutch before giving it gas. Does this mean my clutch could be going out already? the car only has 63k on it...
I did a tune up on my 20th last week, plugs and coil packs and oil change. now i have a strange idle that it wasn't doing before. i checked all the plugs over again and they are gapped fine and i have no CE light on. Every now and then my RPM meter will jump down and then right back up, same with the boost meter at the same time. i had it looked at at the garage i go to and they said they cant seem to find anything wrong. What might be causing the rough idle? keep in mind this only started happening RIGHT after the tune up.
View 24 RepliesSo my car started to misfire when under boost so I had the car scanned the first time and came up with codes P0302, P0303, and P0304 which are all for misfires. I replaced the coil packs not even a year ago and the car drove fine as long as I wasn't in boost. My rpms would fluctuate a little bit but not much. I changed the spark plugs and it seemed to work a little bit but it would still misfire under higher boost. The one thing I noticed was my vacuum sits at around 15-17 in when it used to be around 19-20. I've cleaned and disconnected the MAF and the idle didn't improved. I also cleaned the MAP sensor and AIT and the CTS is new. I've done a pressure test and I found some leaks and fixed them but still no luck. Then yesterday my car started running really rough at idle and the cel would flash while driving then stay solid while stopped. Got the car scanned today and got codes P0300, P0301, P0303, and P0304.

The AC also has problems it blows cold at idle but at highway speeds after 7-8 minutes running the compressor kicks out. One can turn it off and it blows cold again after a few minutes.
View 5 RepliesI went to go get gas today and tried to open my fuel door with he button on my door and it wouldn't open. The trunk opened fine but when I pressed the gas button it made no noise and didn't move at all. I've never had a problem with my fuel cap and all of my locks besides this one work fine. I also can't manually open my fuel cap from the back, because in my GLI, you can't bet much further back behind the tail lights.
View 2 RepliesThe sunroof on my 04 gli just decided to open by itself and now it won't close. Why this is happening?
View 16 RepliesI picked up my beloved 20th last week. It has this feature that when you shut the car off it closes the windows and sunroof. It's very annoying. Is this an aftermarket item that is doing this or is it a stock program? I don't think the car has an aftermarket alarm but I'm not 100% positive.
View 20 RepliesI have an Imola 20th and recently i have been having some problems with my clutch. The pedal goes from being soft to very hard when its close to disengaging. It also engages very heavily when I go to let it out. This only started happening recently when temperatures started to drop if this has any effect on a clutch. Also, I replaced a shift fork two months ago and was curious if there was possibly anything going on with seals around the slave cylinder.
