Default Re: Catalytic converter is bad I think,...

Tingling sounds like it could be an exhaust bracket. Without the engine code it would be a wild guess on the check engine light, but there is a history with the pre cat oxygen sensors going bad around 60,000 miles and only coming on after the engine gets warm. Even if it is the cat, the H2 is exempt from emission inspection in my state because of its gross weight and no one would know if I just ran a straight pipe there.
