My car acts like it doesn't wanna go. Like u press the gas and let off even tho I am not doing so I am keeping the gas pressed and it has a weird smell when it does that. Catalytic converter maybe? It has 8000 miles on motor and 160000 on transmission. We have cleaned the gas tank and checked the vaccum lines. Nothing we've tried has worked
Has the check engine light come on? Have you checked fuel pump pressure to make sure it is within the manufacturer's specs? Have you tried disconnecting the catalytic converter to see if it runs properly?
