Here is the problem : 1993 Buick Regal , it's a 6 cylinder, 3800 and only has 108,000 miles on it. Runs beautiful. But when it gets down to about 25 degrees at night, it will (once every few weeks) idle fast when started (but it will NOT idle down). In fact, if I kick the gas pedal it idles even faster. If I turn off the engine and restart the car, the problem is gone. I have had 2 mechanics look at it and a few people on the Internet have offered suggestions. NO, it is not the Air Idle Control(already replaced), the ECM computer (already replaced), or the Throttle Position Sensor (already replaced). All the wires have been checked, the PCV has been replaced and there are no vacuum leaks. Also, the ohm settings on the Throttle Position Sensor have been checked. This problem never happens when it is real cold outside or if the car is in a heated garage. This is starting to piss me off. Someone must know the answer to this. Please help!
