Question about 1999 Ford Explorer
While driving with foot on gas car fine but when take foot off gas car stalls. Engine also has a pinging sound. Boh oil and antifreeze ok
These trucks are equipped with an idle speed control motor. What you're describing sounds like that part has stopped working. The part is designed to maintain idle when gas pedal is released. Now if you hear an audible hissing noise under the hood, then theres a vacuum leak which can cause the same problem, but it sounds like the idle control motor. Good luck.

that has nothing to do with that,make sure all is connected like the mass air flow sensor and sensor on the intake tube it under it hard to see. and also if battery was unhooked then may need to reset idle, just keep foot on gas for a few minutes if that still does not help then replace the idle air controlm valve, hope this helps.heres a diagram to help locate parts.

The IAC valve is usually the problem with the 1.9 Escorts ,causing a very poor engine idle at a stop. It is located on the side of the throttle body .

you should have the code read with a scanner at a garage Possible (Throttle position sensor ??? (TPS) the code reader will tell you exactly wich sensor is the problem

Sounds like a bad IAC (idle air control valve/sensor) that controls your idle when going from throttle to idle. If bad your idle will act crazy and can cause stalls easily. Pretty sure that's it.

need to replace the idle air control motor on the intake. it is sticking because of carbon build up also you may have too take it to a shop with a diagnostic pcm flash device to reset values for the new part but normally this doesn't have to be done.
