Trouble codes after swap

[afcamaro]

Alright I finally got everything together and got the engine running and having some issues now. The engine will only run for probably 20 seconds at a time then shut off. There is no pedal/throttle at all, it will only idle.

Its a dbw setup and everything but the new harness has come off the same operating vehicle.

Codes that it is throwing are
p1125 fuel/air metering
1516 idle speed control
0107 lost comm. with throttle control module
0155 air fuel metering
0101 maf
0106 map
0155 02 sensor
0135 02 sensor

Im not real impressed with the guy that did my wiring as I found a few simple mistakes that he did in the starter hookup/relay side. Its a rewired 04 sierra harness as is the engine is as well. It looks exactly like a painless wiring harness and color coded exactly the same as well if that helps.

Do you think it could be the ecu bad or the throttle control module bad? I checked the power and ground going to it and they check out OK in the harness, and when plugged in you hear the throttle body flap open.
Any ideas?
Thanks, Adam
