Where is the Idle control valve located :oops:

I want to give it a good clean with some carb cleaner because the revs drop low sometimes causing me to almost stall
 
I dont know, but isnt this controlled by the ECU?

I thought on Kpro you could set your idle rpm etc? Wondered if you cant change it unless its programmable ecu (i.e. kpro)

You can change the idle via K-Pro but think about it....if the control valve doesnt work the ECU wont be able to control the idle ;)

If you find it let me know could do to check mine, as sometimes have the similar problem, although taking it for a blast seams to cure it.
 
As promised

I figured that this would be something worthwhile to add to the boards, considering a few boost guys have complained about eradict idling. The problem is often due to a dirty idle control valve, located on the underside of the throttle body.

It's pretty basic stuff, nothing difficult. Begin by removing the misc. electronic plugs from the throttle body. Remove the two bolts and two nuts, then pop the throttle body off. Turn it over, and you'll see the IAC valve bolted to the underside of the TB. Remove the screws, then remove the electronic portion of the valve. After it's removed, soak the valve with non-chlorinated brake cleaner and work the valve back and forth to clear the build-up. I'd let it dry for at least a day (might be overkill, but oh well, I've got the garage to leave the car in), then reinstall.

I haven't cleaned the valve yet, but will post pics tomorrow night to show a before & after.

Here are the pics:
