I'm new to this so any help would be great. I have a 07 150 FX4 with 4100 miles. I brought it in to the dealership about 1000 miles ago for an oil change and also because the truck would buck when you would step on the gas. The dealership told me the throttle body needed to be replaced. They went ahead and did it and the truck was ok but the problem is starting up again. Anyone have any idea what would be causing a problem with the throttle body or causing it to buck the way it does. Any help would be great.
