When I rev the engine (5.3L) and then let off the gas, or just let off the gas during normal driving, while the air conditioning is on, the air conditioner belt tensioner chatters unusually loud. I have changed the belt and tensioner believing the spring on the tensioner must be weak. No help, the same exact problem. I have searched for answers on line, finding only that the problem is known but no real answers on a fix. There has been no previous maintenance done on the A/C system. The problem started about two weeks ago, no previous history. If you know the answer please let me know, I would be very appreciative.
