Hello,
Heres the problem whenever my car is at idle or in park while running it makes this horrible rattling sound. It appears that its coming from somewhere in the exhaust system. my guess is that its coming from the catalytic converter. but I'm not too sure... Does anyone know what could be wrong and or what the best course of action would be to repair the damaged culprit.
