What's wrong with my Pontiac Firebird and the exhaust and the catalytic converter?
2000 Firebird auto v6 pipes are making weird sounds while in park or driving. A little smoke comes from the exhaust and gas fumes smell. The catalytic converter is shaking and making weird sounds also. I can drive it but doesn't have good acceleration like it did and when I get on it and makes a real loud sound from the straight pipes and service engine light is on but stays on until I get on it or gives it a little gas then starts blinking. What could this be? Any help is appreciated.
