I've taken the truck to a different mechaninc. He says that for some reason, the PCM is leaning out my fuel by 40%, and changing up my timing, while the truck runs poorly. This causes it to starve for fuel, until it gets to wide open throttle. As soon as you hit wot, it overrides the "error", and smooths back out again. He checked my voltage, as well as my ground wires, and couldn't find any problems.
Here's what i've replaced to date:
1 - leaking injector
Plugs / wires / cap / rotor / ign. coil
Down stream O2 Sensor
The problem is less consistant now, but still occurs on virtually every short trip. The only difference, is a longer span of smooth running, in between screw-ups. The truck just starves for fuel, until it practically dies. It has yet to fully die, but it comes really close. As soon as you hit WOT, it clears right up. The new mech. is checking into it, and hasn't given up yet, but I wouldn't mind some additional insight from the wise.
Do these trucks have a reputation for faulty PCM's?
