Did you do the mods to the truck? did this problem start after the mods?
I would think with bigger injectors, you should probably be running a custom chip from someone like TW, PHP, DP, Swamps, etc. That might be causing the misfire sound.
As far as the ACC sensor, I think you can hook an Ohm meter to it (while disconnected) and slowly go from idle to full throttle and see if the meter has a nice smooth change in numbers. If it jumps around then the sensor is likely bad. I was also thinking that these trucks have another switch on the ACC pedal for telling the PCM when the pedal is at idle. I could be wrong on that one though.
