High rev when a/c has been on for a while?
Iv'e noticed lately that when im driving and my a/c has been on for a while that my truck revs up when i push the clutch in to change gears or when i put it in neutral it will rev up. It goes up to about 2,5k for about 3 seconds, then it will drop back down to normal idle. It only does this when the a/c is on, and as soon as i turn the a/c off it stops. It doesnt do it when i just turn my a/c on, but after it has been on for a while. Has anyone else ever experienced this or knows what i should do or check?
