So for some reason I'm Thinking It's the Catalytic Converter now. I'm thinking something had made it hot, and it melted the catalyst inside the cat and now Exhaust cant get through. That's the only explanation for the way it's running. It feels way constricted. maybe??? Where Can I buy A dummy O2, so if I strip out the cat, or put in a test pipe, I dont get a Check engine light???
