Popping Sound
My '91 Z has a popping sound coming out of the exhaust at idle. I don't have a service manual so I was wondering if anyone could help me out? It is a slight sound and only occurs when engine is warmed up. I am not showing any codes and everything works. It seems as if it is only performing at about 95%. I'd appreciate any help.
