I've got a few ideas, Check tire pressure's, check wheel bearings, check to make sure the brakes aren't dragging, run lighter oil in it. If its not running well it could be a plugged cat. Does it have the 5.2 or the 4.7? any check engine lights? How did you run the seafoam through it in the tank or in the brake booster?
