Random no start, no engine rpm increase
I have an 05 excursion with the 6.0L. I have gone to start the truck and it will chug for a bit and shut off. Eventually it did start but when I went to accelerate there was nothing. Pushed the pedal to the floor and nothing. I idled along for a little bit and all if a sudden it started driving normal again. Went out this morning and it started normal and drove normal. I have an Edge insight but not sure where I should be looking. I brought up the accelerator position sensor and EGR pids but not sure what else I should be looking at. Also I noticed the voltage at idle was around 12.5 volts but anytime above idle went to 13.5 volts. Any help would be greatly appreciated.
