89 Cress. Stalls after warm and driving

[jakestj]

Any idea's? Car runs fine cold but after warm and driving engine will want to stall at low RPM's. IACV? I'm working on the car, it's not mine. It has not been able to produce the problem for me. I hate the cars that have intermintent issues. All hoses look good , can't hear any vaccumn leaks.

Cold be the IAC valve. Might be a coolant temp switch issue.

first guess would be vacuum leaks, they can be there and bad enough to stall the engine without being obvious. coolant temp sensor is my second guess.

I've never actually heard of a IACV going bad on a cressida.
