Lately, after driving with the AC on, when I come to a stop and put the jeep in neutral, the engine will be idling over 1000 rpm, which is higher than normal with the AC running. Typically the jeep idle is around 750 RPM with the AC on. It only does this while the AC is on. Any ideas what could be causing this?

I did try to, but I had trouble removing the IAC from the throttle body. I removed the one screw holding it in place, but then I could only the sensor to rotate about a quarter of a turn in the sensor housing, but it would not come out. I did not want to use much force to pull it out until I consulted the forum here. Once the single retaining screw is removed, should it pull straight out of the housing or do I need to rotate and then forcefully pull out the sensor?
