Every time i get out of my car it smells like un-burn't fuel. Or whenI have it sittin in the shop standing 10 feet away you smell the same thing.
I'm not sure if it has something to do with the aftermarket exhaust or just runnin to rich. On the emissions tester NOx is high so I'm thinkin posible EGR.
Anybody have any other thoughts? :confused:
Thanks -Wes-
Jump 10 and GND to see if you are throwing any codes. Do you have an exhaust leak? Fuel leak? Has the Fuel Filter been changed? Maybe a bad o2 sensor.
It was an O2 sensor for me when I noticed the same thing.
You're O2 sensor was already defective on your car? :confused:Quote:

I am running richer due to the great flow of exhaust. Have spares waiting to go in right before inspection, but no codes alerting problem.
Yes you do. You were the loudest competitor at the last two events I attended ::Whisp::Quote:
