Having problems with your 1996 Ford Windstar ?
Wont idle when hot - 1996 Ford Windstar
Possibly the idle air control
I would check that the coolant temperature sender is working OK. If it is under reading then the ECU will be sending the incorrect amounts of fuel to the engine making the idling lumpy.
