Hi guys. I'm having an issue where my car will not idle and has codes P0122, P0223, P0113. My tuner has spent hours on this thing and he can only get it to idle by bumping the base idle airflow WAY up. He says something is seriously wrong and won't continue with it until I've figured it out. We've swapped MAFs, PCMs, throttle bodies, gas pedals. I've traced all the wires on this harness and compared it to the GM wiring diagrams and everything seems to line up. My next move is I'm going to get a wiring specialties harness and hope the problem doesn't follow, unless someone has any ideas.
