I just fixed my exhaust leaks with a little high temp quick steel. It was leaking where the y pipe and cat meet and i had a 4 inch crack on the converter. Fixed the leaks and the car was much quieter. When I took the car for a drive after that I could hear rattling around that area, the car smelled like rotten eggs, it shakes bad, has no power and feels like its choking and there's plenty of hesitation. My guess is that the cat is bad. Anyone else?

 

I would say that's a good assumption

 

pretty good bet , if its factory how would it be ? 30 yrs. old , already its bad . just a joke . rod it out , ditch it , or replace it . good luck .

 

sounds bad to me. mine cracked around the same area :-/
