1991 Corsica with intermittant loud put-putting exhaust
Ok, I have a 1991 Corsica with 70,000 miles that doesn't owe me a dime. It has a 2.2 engine, TBI. About 2 years ago I put in a new exhaust from the cat back. I will try my best to describe an intermittant noise that rumbles thru the exhaust, like a loud high pitched fast put-putting. (I think thats it!) the noise comes and goes at idle or while running. when the noise is not present, it is quiet. Then the noise kicks in and as i have listened closely, it's not muffler related. (That was wrong) It almost seems as if is from the engine, but could it be cat related? I'm thinking engine since it is intermittant, not continuous. Any advice will be appreciated.
