Ok so I am having major problems with Idle.. I am currently Idling @ 2200K and 3000K after warmed up. My Vacuum Lines are good and have no leaks I had a check engine light and found the IAC was bad as well as the front o2 sensor. I have since replaced those. I looked up IAC in the wiki and found nothing useful for my problem outside of cleaning the TB. I know there is another sensor above that I believe is the Idle speed (stepper) while driving the car I have to ride the breaks in 4th gear just to maintain the speed limit. the only thing I can think of is when you get a new IAC do you have to adjust it? If so please explain how to adjust it right. thanks in Advance guys.

Ok I think was reading up on Google and, the pintle needs to be 28mm away from the stepper motor? Also the sleeve under the pintle, dose that need to be pushed down and, stay down?

I thought the IAC had a "home" setting. You could also try the turning it and not plug it in so that the ECU can not interfere with where you position it. I had a small idle problem and did that as a temporary fix. Just make sure you are up to operating temperature.
