avalanche help needed desperately
About a month ago, my 07 LT died on me. it gave me "Service Stabilitrak, service traction control, low oil pressure, reduced engine power, stop engine".
I erased the codes and it ran just fine for about three weeks. after driving for about 4 hours it did it all again. I disconnected the negative terminal and reinstalled it and it got the last two hours good to Arkansas. I had a new ecm programmed and installed at a Chevrolet dealership, and on the way home from Arkansas around 4 hours into the trip it did it again, in which I put the old ecm back in it since the codes were erased due to not having power. Now it wont do anything with either ECM, and I have No idea where to go from here. Ive heard anything from throttle body sensor to throttle body connector to on star computer

Grounds? Fuses?
That must be annoying. You're probably best off taking it to a Dealership though - electric problems on advanced trucks like yours are tough to work with.
