Hi guys,
I am having a really bad idle problem. My car idles 1300RPM or higher. I have done the IAC reset procedure multiple times. Replaced all gaskets on upper plenum and intake. traced out all vacuum lines and eliminated those as possible high idle issues. The IAC is at zero at idle with the set screw all the way back on the throttle body, no matter were the tps is at it idles high. I can disconnect the IAC and try to adjust idle with throttle body and it does nothing below 1200RPM. How can i tell if the IAC motor is bad??? It moves off of zero when crusing but at idle it drops back to zero. Is 0 fully closed or fully open??? I have been struggling with this for a good while now, any help or ideas would be great.
