1779 and 80 may be a tcm problem or the can network not sending signal to the tcm 1795 may be the same thing or the gas pedal is causing the problem for all three. 2176 is the throttle plate positon on engine but the gas pedal may be causing this as well cause it's not getting a good signal have a local pro hook his pro scanner up so he can get a better idea because he can do things with his the auto parts type can't.
