Off the top of my head, I think it's the PCM (Power Control Module).
I have a question, my truck runs good most of the time (I notice a little hesitation about 20mph in 2nd and 30 mph in 3rd (no tack on dash), which is about mid-throttle up (so probably when the engine is passing the 2000 rpm point).
The voltage going to some of my modules (probably all of them), for sure the Throttle Position sensor and MAP sensor, is only like 3 volts, not 5. I would have thought the truck would run porely like this.
Anyone have experence/knowledge of having to replace the PCM in this situation?
(BTW, I have a new MAP sensor and Throttle Position Sensor)
