95 Contour 2.0 Liter, 137,000 miles. Eng rpm drops to 500 rpm when stopped and in gear (auto trans). Problem is compounded when A/C compressor cycles on. The car has been to the dealer for this problem and they have been unable to fix it. I also had an independent look at it for a few days. The idle air control motor has been replaced/no fix. Idle problems seem to be a common complaint on this vehicle. Got tired of the Ford dealer throwing parts at the problem. Do any of you have any suggestions as to a fix? I have been driving the car with the problem for a couple of years now. Otherwise has been a decent vehicle. Thanks
