Will a missfire cause your car to fail the smog check?
I'm not sure what is checked during a smog check. In the UK we have an emissions test. If the vehicle (petrol engined) has a miss fire it will bring the carbon monoxide level down. But in doing so The hydrocarbon level will rise. That will cause a test failure
