Default 2000 caravan iac problem

I have a 2000 3.0L caravan. The iac is not adjusting. Installed a new one. Still not adjusting. Installed a pcm. Same thing. Idles high and surges when in gear with the brake on. Any suggestions on how to fix it.

Have you tested the wiring connecting the two? Have you tested the ECT sensor, checked for vacuum leaks?

I believe the wiring has been tested but not sure about the ECT sensor or vacuum leaks. A friend is working on it for me. I will check with him.
thanks
