I was driving my Montana today and all of a sudden the SES light came on and the vehicle had no pickup and was sputtering somewhat. Only have 38K on the vehicle and haven't a clue as to what might be wrong. It was running fine until the light came on. Any easy way to find and read the code. I'm guessing the computer went but I'm hoping that it's not that as I know it will be alot of $$.
