I took the iac out and blocked the port it came from. I wanted to see if the pcm would control it. Started it up and the iac never moved. I tried two new iacs and nothing. I would expect them to move trying to reduce idle air.

I figured out that tge iac never moves. I have put 2 brand new ones in it. I can pull the iac out abot halfway and it will idle ok. But it will nearly die when i put it in gear. Maybe bad pcm?
continuity check the circuit?Originally Posted by cottontop11
Yeah it ohmed good. I tried to measure voltage could not get anything. Pcm on the way
I am sure you already checked this.The cable driven throttlebody has a set screw to adjust idle.
Yeah it was idling at 1000 with it all the way in. Im not getting any output to iac from pcn
What PCM do you have?I'm sure you know but some PCM don't have the IAC drivers...
