HELP: my 1996 M3 failed emissions today
Hey guys,
I failed emissions today with the Bimmer. Its a 96 M3 with a Shark reprogram, intake, and tri-flow exhaust. The check engine light is NOT on, but it failed emissions today as a gross polluter because of the extremely high NOX levels. Would this mean a bad cat? What else could it be? I'd like to narrow it down before i take it to get fixed so I can maybe save a little dough. Any and all help appreciated.Taylor
ps-what kind of negative effects is this having on the peformance and gas mileage? [???1] [???1] [???1]
