Irratic Idle

[scott-mk3 0]

So i cleaned the throttlebody on the vr6 iv got the now and the engine was out as i fitted a new clutch however i now have the problem of a bad idle.

Iv searched about and it seems that i somehow need to reset the idle position on it to let it know its proper idle. Its obd2.

The car will idle between 1k - 2k as if its hunting and then if i disconnect the tps and icv it will settle for a little while then i plug them back in and it idles where it should. However then on taking it a drive the idle on coming upto junctions dies almost fully if not stalling.

Any help appreciated.

Simply turn the ignition on, without starting the engine, and let it sit for 15-20mins. You should be able to hear the throttle body going through it's paces.

This happens to mine but only when cold. I let it set the throttle body but then when I start it it idles high :s it's almost as if the ecu forgets everything when I sworn the engine off. Sorry to hijack btw

Tried leeving the ignition on for 20mins then starting it but still didnt make any difference. Not even sure if there was any noises coming from the throttle body.

The car hasnt been driven in a while if this may cause any problems? I took it a 20 mile drive and it started to idle better and where it should however occasionally on coming upto junctions and putting the clutch down it would stall as not knowing where to idle.

Anymore help appreciated
