Idling prob

[mikey 0]

Every now and then when I dip the clutch the revs drop dramatically and the throttle either can't deal with it and the car dies or it over compensates and revs up and down a few times before settling it's on a turbo running c2's stage 3 chip

Any Ideas ???

is it OBD1 or 2. Could be the idle control valve sticking a bit. I know they can be a problem. Had to do mine once or twice.

Can be sorted pretty easy with some carb cleaner or something poured in it, give it a good shake and soak. Just make it's 100% dry before re-fitting it.

Oh right cool it's obd2 I thought it was somthing that could be reset via vagcom I have plugged mine in and don't have any fault codes but I only have a shareware version !!

if its an obd2 you wont have an idle control valve mate so the first things to check/do are clean the MAF and check the state of the throttle body mate

Ok well the maf Is brand new and the throttle body was all cleaned before it went back on ?? :-(

throttle position sensor might be faulty but I would think that would throw up a code on vag-com

Have another look inside the throttle body to ensure there is no oily deposits or gumming.

mike you gor dv ? if so it needs to be a recirc, or as you have a maf , this may happen..

otherwise its a airleak, retighten all connectors and double checks everything

No dump valve jim but I also suspected air leak but snow has stopped play

Right I don't seem to have any air leaks and connectors seem good but I have noticed that if I rev it but not hit boost it's fine but when boost is made it revs down real lumpy almost with a miss no fault codes at all ??
