Well I have been doing the Idle problem searching as many know but I have come to completely suspect the IAC.

When I have the car to the on position, not running, I can get 12 volts from the IAC terminal and a ground point and across the IAC clips terminals. However I can not get a continuity reading to ground with the car on.:wtf:

Heres the Question:

If I can get a 12 volt reading across the clip doesnt't that mean the ECU is getting a ground for the IAC? The ECU was replaced by a dealer for not having ground.

If the IAC clip is pulled the idle does not drop at all.
The IAC's resistance is within limits.

Well this is my last attempt to fix it before trading in the car for whatever I can get. So hopefully someone can hewlp me out!
