After I drive for about 5 minutes or so, the car smells a lot like the catalytic converter. The check engine light comes on, the car loses power on acceleration, and sometimes sputters and backfires. There is black smoke coming out of the tailpipe. The diagnostics wouldn't return engine codes, only that the mass air flow was malfunctioning. I am at a loss, its not the pcv valve either.
have the same problem?
