Jason it was my PCM, now the one that I sent for did not work, so I put it in the shop, to the tune of $ 544.00 bucks. They put a new one in and flashed it to my VIN and did the crank position relearn with a tech 2 scanner and it fired right up. Now what I have noticed is, I am burning less fuel and I can now here the air roar through the engine. And the voltage meter is no longer fluctuating, that went on for a long time, I thought that it was a failing voltage regulator or a failing diode in the alternator. Before the PCM failed I cleaned the Throttle Body, and it ran better, now with a new PCM in, and a clean throttle body, after the PCM learns it, my engine will continue to run great, and smooth. now I have to get it ready for the winter, I just put Mobile one full synthetic in there, now I have to change the Dex Cool and put on some more ceramic bracks and some spark plug wires and I will be good to go. Driving it for for a little bit the PCM will learn the truck and my driving habits and I am good. Here is some great info on PCM's man check it out.
