s/n AT35
OK. This truck has had a history of engine overheating and I was sent out to clear a e33 fault code. While I was hooked up to the diagnozer , and this being my first time out on it I decided to check the throttle sweep and compare the throttle angle adjustment to accelerator angle. At full throttle it should be with in 8 to 10 percent of each other. I was getting 22% and 77 %. I have run across this before and easily made adjustment to 94/100%. Creating a much cooler running engine & more take off power in which I noticed this was weak. My problem I run into was when I made the adjustment I needed and gave it full throttle the engine would surge on me like it had a gov on it. Cleaned a dirty screen in the throttle body but no help. Has anyone ever run into this?
thanks in advance
