The code is P0650 Malfunction Indicator Light (MIL) Control Circuit . The only things the car has been doing every so often is the cluster not lighting up the idiot lights and then it won't start. I turn the key on and off a couple of times and its back to nomarl.

 

no body has had this issue before or this code?

 

im guessing not. almost sounds like this G5 that came in to my work. i have no idea on what the chevy dealers doing with it. good luck tho

 

I think i found the issue.I had my wideband plug into my fuse box in the car and I unplug it and the code has not came back on.I wonder if the bcm is going bad?
