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.
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?
Thanks -Wes-

It was an O2 sensor for me when I noticed the same thing.
I live where even the coyotes won't go...
Do O2 sensors go bad and not throw a code? I noticed mine directly after replacing to full race exhaust and header. I need to take the test pipe off just to quiet it down a bit. 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.
Yep, going back to old cat instead of test pipe. The extra 3 horses isn't worth the attention.
