Since it was a perfect day here in NJ I started my car and had the windows down and the stereo off. I hit the gas a couple of times and I noticed a rattling noise from the engine and the RPM's came down. I remember Billy saying this was a pretty good sign of a beat tensioner so i checked it out. I had the hood open and sure enough every time I hit the gas as the rev's drop I get this odd noise from the timing belt side of the motor. It's not the same noise all the time though...somietimes it sounds like a rattling and other times it sounds like something rubbing against the cover. I'm going to get it in sometime next week to make sure but does this sound like the auto tensioner problem?
