Recently I replaced all 8 injectors and the CP3. The CP3 has an LBZ regulator.
After I got everything replaced I started the truck and drove it around before re-tuning it for the LBZ regulator. The truck would throw a P1639, P0237, P0107. The truck would also randomly get a dead pedal. You could clear the codes and the pedal would stay the same. I would have to cut the truck on and off about 15 time before the pedal would come back to life.
Now on to yesterday. I re-tuned the truck for the LBZ regulator. The truck is now only throwing the P1639 code (it is not throwing the code all the time) and will get a dead pedal. You can clear the code and start the truck back up and the pedal is back to normal.
I have re-tuned it 3 different times, checked for chaffed wires, replaced the APPS on the pedal.
Anyone out there know of anything I need to check that I have missed?
