first code said throttle body. I replaced it and no problems for two months. Problems started again. Last code only had the pedal assembly listed. Replaced it today and it seemed better but still threw the wrench light. If it gets rough enough the engine light will come on and once it said transmision fault.

Power loss is like having water in gas or a clogged fuel filter. truck runs rough, speed drops, tacks a little high in spurts, then clears up and runs fine for a short time.

Do you know the code numbers stored now?

Are you behind on any maintenance like filters, tune up, cleaning any systems?

gonna run it in the morning to see if any codes turn up. maintenance up to date. starting to think maybe a computer problem.
