Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Last owner gutted the cats and put some kind of race exhaust. It's annoying to be honest. I need to get the car smog'd soon but I keep getting a check engine light with codes po446 and po430. Anyway to get around this turning on the check engine light? Or is my only course of action to replace the cats?
