99 windstar 3.8 stalling at lights

[greenwindstar]

my windstar is stalling when idling in park or in drive at a red light. it also bucks like it wants to stall when driving down the road. I have read to check the Idle Air Control and reprogram the Power Control Module. Has anyone seen similar problems and have any solutions? thanks!

The IAC (Idle Air Control) valve is a common culprit in Windstar idle problems. I don't bother replacing it: A quick cleaning with a decent cleaner (I prefer Berryman's) and it smooths right out.

I replace mine. I still have the same issue sometimes similar to the original poster. Was their another step I missed?
