Re: O2 sensor
I would not expect any knock on a stock car but many things could be causing it, have you always been filling up with premium? I believe that the ecu uses the front O2 sensor to detect rich/lean so maybe it is possible that it is causing the knock if that is true but for some reason I doubt that just a bad sensor would cause knock on a stock car.
