Excessive Cycling of AC Compressor Clutch on Ford Aerostar

Excessive cycling of the AC compressor clutch when the system is fully charged could be caused by sludge that has built up on the engine throttle body. Throttle body should be cleaned periodically unless there is a sticker on it stating no cleaning is allowed. Some throttle bodies have a special coating that should not be cleaned.
