I'm pretty sure its still the rich light. Hell I think the car is only getting about 15-20MPG highway...something isnt right.

I just drove about 45 miles and used 1/4 tank, that can't be right. I am really not hard on the car, keep it below 3500 unless I need to shoot out onto the highway, then I will push 5K. But other than that I can't see how this car is getting such bad gas mileage.
