My car smells like gasoline. Whenever I am first starting it or standing behind the car outside it smells like fuel. Performance is fine, and I am getting ~27 MPG. The engine does not feel like it has a problem. I would assume the O2s are fine, and I can't seem to find a fuel leak.
I'll go out to start the car (With the garage door open of course) and come back after locking the door to the house, and the garage reeks of gasoline. This car is running rich. Very rich, but why? I hope it passes emissions.
