    Welcome to the club!! It is funny how either removing or rplacing the gas cap can make a difference in the operation of the truck. I would aslo suggest that you check the Q&A section. I wish I could be of some help on this subject.

    When you remove your gas cap, is there a vacuum in the tank? Maybe excessive pressure? Does it "Suck" or "Hiss" when you open the cap?
