I have an '02 3.8 automatic with about 59k miles. The check engine light is on and of course won't pass inspection. All the print out from the shop says about why I failed is, Catalyst. I dont know much about cars, I am assuming they mean the catalytic converter. I just bought this car a year ago, and the person before me put a K&N air filter and dualed out the exhaust.
Do you think it may be the aftermarket parts causing the problem?
I'm dead broke, so I'm thinking of disconnecting the battery for a while to reset the engine light and have it reinspected. Maybe I can sneak by until I have the money to fix it correctly.
