I keep getting comments about a very strong gas smell when I accelerate hard. It is only smelt behind the car. Car has a return fuel system. How does the vent system work on these cars? That's the only place I can think of that the issue may be from since I can not smell it in the car or when exiting the car.

Without cats the fuel smell is going to be strong. I've been behind plenty of non catted cars and they have a bad fuel smell when accelerating.

are you running cats?

Some people just aren't used to smelling a car without them. A friend of mine kept swearing that my car was rich, even at idle. I kept telling him that its just because I have no cats.

Once I installed my wideband I let him take a look....14.6-14.7 at idle.
