I posted in here and the diagnostics section to hopefully get a faster response..... so i got my cam/stall and tune on my truck done about two weeks ago. itys been driving flawlessly since then. i even took it to the track and made a few runs in it, still good. i drove it last night and parked it at a friends house. i wake up this morning to go start it and it goes into REP mode, and then the idle starts to climb up to 3k rpm and stays. i disconnected the battery twice and it wont clear it. i am also getting these codes:

p0068 maf/map sensor throttle pos, correlation
p0120 tps/pedal pos. sensor a circuit malfunction
p0220 tps/pedal pos. sensor switch b circuit malfunction
p1516 manf cntrl veh spd idle speed control aux input
p0106 map/baro ckt range/perf

i have no idea what is going on and its driving me crazy. any help will be greatly appreciated.

Check the wiring going to the throttle body, the TPS in particular, might have a broken wire or an animal may have eaten through the harness. If that checks out OK, I'd be troubleshooting something wrong in the throttle body area from the sounds of those codes.

Disconnecting the battery will not clear codes. Your TPS is toast.

well i changed out the TB and cleared the codes, truck fired up first try and runs great. upon inspection of the old TB it looks like the bottom half of the blade. i measured with a digital caliper and there is a .223" gap between the TB blade and the housing>>>how the **** did that happen?
