After hard acceleration, my exhaust has a "gunpower smell", what causes that? I have smelled it over the years from pther cars, what gives.....
Yeah, Sulphur is more accurate. The o2 sensor is new and heated. I'm running EBL and still dialing in the new motor, better post my latest datalog for rBob or rocko350 to look over.The mixture may be a little off. The sulfur smell is akin to the rotten egg smell. Your O2(s) may be on its(their) way out.
