Well I took the truck fer an after noon drive I thought the prob about the hesitation was gone becuz it hasnt done it in a couple of days. Well riding down the road it acted as if it was going to go dead acceling from 35
It also does it when i give it half the pedal from a stop the truck will push me back in the seat and them act like it's going to die then come right back to life. I dont know How much does a TPS cost? DOes this still sound like the prob? I dont need a tune up. I do however need a rotor button and i dont need a dis cap but it would help. Please help me. It accelerates and drives fine as long as you barely give it any gas? But if you drive to drive it using a little bit of pedal it doesnt wont to run. OH it's a 318 TBI 1988 model 4x4 1/2 ton truck
