Engine Mechanical problem
1999 Cadillac Deville V8 Front Wheel Drive Automatic 111000 miles
I have a 1999 Cadillac Deville D' Elegance. It stalls every now and then at a red light or while parked. I noticed when the RPM is above 600 while idling it's fine. Once it drops under 600 the car stalls. It turns right back on with no problem. My question is would this have something to do with the throttle sensor or idle air control valve? I took it to a mechanic and they have no clue. They keep changing one sensor and when that doesn't work they put the old sensor back in and change another sensor.
