Thanks guys I changed the TPS as I had one. While doing that I found the EGR valve was rusted away the stem was all that was connected no spring Changed that. Idle is a bit high but no more surging. Bought this truck about 10 years ago and use it for plowing the drive way and hauling wood. I changed the front pad and the clutch. I figured if it runs why worry about it . Guess I'll treat it to a tune up now so it's good for this winter.
