has anyone here having issues with the tps on 08 f-350's? i bought the truck in august 09, stock with low miles. the fuel mileage sucked so i added a sct livewire and dpf delete. mileage was up to 17.4 and working great. just three weeks ago the throttle would not respond above idle. i shut off truck, restarted and it started working.this happened twice. recently it happened again. this time the check engine light came on had i had to reprogram to stock to get truck to operate. also threw a u0115 code. i put the dpf back on, cleared the code and not had an issue since. i feel like it has to be the programer, called sct. told me the egr is goin out. i'm going to run it stock for awhile just to see if it happens again.
i really want to get the mpg's back. hope you can help.
