So you could imagine if there was a problem with this valve then it would cause idle problems. It may just be dirty...
It quiet possibly could be a number of things though... Definately something to check out though. I cleaned my IACV on my DA9 and i still have a quiet high idle, up around 1500 RPM.
Hope this helps in some way??
Also check your throttle body...
must be ur idle air control......touch wood, so far my dc2r dont rev over 1500-1600 on cold start untill its warm and drops to 1000-1100
another thing, if your throttle body is stuck slightly open more than its supposed to be it will be letting air through and your engine will be revving up higher... could also be the issue although probably less likely...

thanks heeps guys it has to be something around there cos i recently put a new turbo in with water cooling and i 't peiced' off that water hose on the 2nd thred so im sure its got something to do with that..ill give it all a clean and see how i go. cheers everyone.
Guys The problem went away for a while but then came back and now its really bad, its embarrassing at like traffic lights etc. Got a vid of it.

I did what a couple of you guys said and still didnt work. My mates a mechanic and he also said has to do with that water line that goes from the block to the intake manifold and when its blocked the idol goes crazy, but ive flushed it every which way and made sure water was flowing threw my turbo and back and all seems to be fine.
heres a vid of what happens.

If you guys have any suggestions...also im not to sure how fast the water should be flowing threw that tube to the turbo and back...to me it seems fine but i dunno.
omg thats hectic! It sounds like the ECU is reading bad data and trying to adjust the idle in a loop. I doubt its a simple IACV or FITV problem, the effects of these going bad are much more subtle.
Have you tried resetting the ECU and checked for ECU error codes?
Nah got Power FC...hadnt checked the sensor checker thing on that....might try that i guess.Quote:

If it's the IACV then it might go away if you disconnect the electical connector? Another check might be to take the IACV physically off and plug the two apertures in the plenum, then start it up to see whether this stops the high idle.
Nah its not VAC or intake leek...its more of a distinctive Idle change, not just a rumble going up and down. It used to be the case where when it was cold it would start doing it for about a minute then it would go away. but now when you turn the car on cold or hot it will do it and even threw a 30 minute journey it would still do it.
Checked the sensor setting on my Power FC and i don't know for sure what im looking at to see if anythings wrong but it seems to be fine.
