My 03 Quad Cab with the 4.7 is not running right at all. Ever since I was in the accident with the mustang and most of my front end was replaced, and fan, fan clutch, radiator, radiator, bumper, hood it hasnt been the same. Shortly after getting the truck back from the body shop, the CEL came on and I ran the codes on my superchip and I got p0456, Evap Leak. It has now started to run very rough, and I'm getting the worst gas mileage I've ever seen, around 8mpg. Anyone have any suggestions?
