I was driving around today, when my engine light came on. I called OnStar and they did a diagnostics. It came back with a problem from the drivetrain sensor. The Engine Fuel Contol System had a problem. I havent done anything regarding the fuel system. Ive raced a few times, but should that happen? Also, what the hell does it mean. My dealership is closed on saturdays. Any help/suggestions/insight to what the problem might be? Thanks

 

just take it to the dealer

 

let me just say how fkin sweet it is that they can tell what problem you have while you are driving your car onstar is fkin sweet! lol big props to GM for pioneering the way with this technology
