i noticed that when I rev the engine while in park I cant hold it steady. The rpms go up and down and at times as soon as I slightly open the throttle rpm drop to about 400 and stay there until I take my foot off the pedal. I set the tps at.47v and did a sweep and it seemed to be fine. There is times when the idle surges when parked so I took off the aic and cleaned it, didnt really change. Since I know this car is speed density, im leaning toward an air leak, which would make sense. Any ideas?
have the same problem?
