I have a 1995 Mystique V6 with a 3000 rpm idle. I have replaced all sensors, rewired and insulated all wires I could see, replaced IACV and tried two remanufactured ECMs. The IACV gets a continuous 12v. I have put some resistance in the line to bring the idle down to 1100, however this is not the right way to run a car. Anyone have any ideas?

Is it possible your cruise control is stuck on? Another possibility is a sticky throttle cable.

My thought is that there is a short or the curb idle has been messed with causing the ecu to command the iac wide open. Have you tried to disconnect it while idling?
