89' 325i Automatic.
Recently recharged the A/C and started running it for the first time since I bought the car. I've noticed that when I run the A/C the car idles (or revs) very inconsistantly. I'll put the car in park, and the engine may idle at just under 1000rpms, or it may shoot up to over 3000rpms.
It'll rev up, kick down, then rev back up again. I can even feel the uneven revs when the car is in gear, but it's not as obvious because the drivetrain keeps the car from overrevving. What could be causing this?
