warm engine stalling

My wife's 1995 90 starts up fine when engine is cold, but will not idle once warmed up to operating temperature. I've removed and thoroughly cleaned the idle control valve with carb cleaner, but problem still exists. Any thoughts?

Leak in the intake system somewhere? ;O)

One of those plastic or rubber items?

Or just a bad ISV?

Does the car run any different with the ISV disconnected?

What inside the ISV can cause a malfunction? Anyone ever take one apart to see?

Not going to try to fix mine. I thought they were pretty fail-safe as long as they were clean.

Re: IT's just a valve.

Similiar in theory to an IAC valve on a GM, or the idle valve on a Ford, the valve gets gunked up with oil and carbon and starts to stick, causing either too much or not enough air on idle. You clean it and WD40 it to lubricate the valve, and you're set.
