is this the only code your showing? I kind of had the same problem last week, but i had codes for mas,barametric circuit,coolant temp circuit. It ended up being the ecu.

Yah this is the only code it is showing. Im going to try and swap ECU's and see if thats the problem.


But i think i might go GM MAFT now blow thru because of this.

it could possibly be the wiring harness for the mas, but doubtful if its in good shape.

Did you actually clear the code and it came right back?
