I started up my car after work and and it had a super low idle it almost seemed like it wanted to shut off. I brought the rpms up to 2k for only for a few sec. Let off it was fine? It was cold out. But its never done that b4.
It almost felt like it was bogging out. I have brand new air filter. And spark plugs.
I just put on a magnaflow cat-back exhaust and sometimes when i idle i have a rattle and sometimes it will not rattle. I went under it and shook all around to see if anything was hitting but there was nothing i could see. What could it be?
View 4 RepliesI don't think I am in the right forum but I don't know where to post it. I have a 20th and when the car idles it shakes a little but when I take off the car rumbles alot the only way not to make it rumble is rev it to 1500rpm what can it be causing this?? I have a catback tt exhaust can it cause it to do it?
View 1 RepliesI've been fixing some boost leaks and changed "race" valve out to the stock "f" type...drove down road it's awesome put it back into 93 mode apr chip give it hell in 1st and 2nd then turn onto another road to repeat and when comes under boost it sputters...like a bad coil pack but wouldn't that mean it sputters from idle up?
View 3 RepliesLately, every once in awhile my cars idle will drop and the car acts like it will die, but never does. I tried turning up the idle +50 with v-tune to see if it would cure the problem, but the car still acts like it will die during idle.
View 2 RepliesSo my car has 67k on it, is babied and taken care of. She runs good however at idle, she seems to put out small little backfires. I just noticed this a little while ago. Sitting in the car I can feel when this happens, it's like a small quick sputter but I'm getting no noises from the engine when these fluctuations happen. The exhaust from almost up by the DP back to the tailpipe will move with the sputter if that makes sense. Seems like it's a slight misfire but im not really sure what it could be. runs strong and the temp always reads normal and I am getting no CEL.
View 18 RepliesI have an 03 20th AE GTI, and I just had the crankshaft fixed. My car now smokes, and I thought it would stop smoking after a few hours of letting it run, but It still smokes, at Idle. and once I step on it after Idling, it smokes alot. but after constant driving, like on highway, It doesn't smoke.
View 8 RepliesMy cars runs great no smoke unless i let it idle for a while then go there might be a little white smoke or blue smoke just depends, doesn't do it all the time just random, my oil is perfect no water in it so I don't think headgasket, its running a precision 50 trim bigger injectors and full 3 inch exhaust.
View 3 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 RepliesSo 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...
Have 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 RepliesWhile starting up the 337 this morning, I received a stumbling idle from the engine. I popped the hood and noticed that there was a bit of bluish / purplish discoloration on the tops of the coilpacks. Gonna replace the packs and plugs today, just wanted to know if there was anything else I should check for.
Also, this wouldn't be related to the death of the driver's side door lock module would it? (I noticed that when i opened the door, the light and the fuel pump didn't prime....)
I have a mk4 gli and I'm having a problem with serpentine belt squealing when I'm at idle and when I turn the ac on. It's isn't all that loud at idle but when I turn on my ac it gets real loud. My ac stopped working a little but after this noise started to happen. Could it be possible that it's the bearing in the compressor that is making it squeal or could it be somthing else?
View 2 RepliesThe 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.
I got a 20th with 83k on it and when i let it sit at idle for like 10 min to warm up after i get in and give a little gas it smokes a little bit and smells like burnt oil.. would this be the case that my turbo is going bad??
View 3 RepliesI have a 03 20th ae gti with about 84k just replaced the coil packs. driving on the freeway then power just goes away, press on gas and nothing. limp it off the freeway. Then it starts to die at idle and hardly turns over. car is pretty much stock. new clutch at 75k.
View 8 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 just had the Eurojet TBE installed and I notice the exhaust rattles loud at idle and startup... I want to say the piping is hitting something and causing this.... should i hang the exhaust higher.....
View 9 RepliesI 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 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.
View 6 RepliesI recently installed the apr turbo compressor inlet hose and eurojet smic on my 20th. I am running apr stg. 1 software on apr diverter valve. I also have 3" ghl turbo back exhaust. The three codes I am getting triggered shortly after the 2 upgrades I mentioned above we're installed. In detail the codes read specific:
-idle air control system: RPM higher than expected
-bank 1 mixture adaptation(add): system too lean
-turbo/super charger: overboost condition
When the car idles it seems to miss every now and then I think cause the fuel mixture. It also does idle higher than it did before (~900rpm) when the cel comes on it seems to fix the missing issue but not idle rpms. I am running the stock ko3s turbo and am soon planning on a Eurosport cold air intake. Am I harming my engine? Can I get the light to stay off?
