TIA for any help I may find here.
So cliff notes: 2012 Maggied LS3, Slight hesitation/mis-fire on hard acceleration at times. Went into LIMP mode, pulled over and shut it off. Car acted like a dead battery. No crank, lights dim. Jumped the car and it ran and got me home. Replaced the battery and the mis-fire was gone. Figured it was an old battery, and it was. Drove the car yesterday (two weeks later) and it did the same thing and gave me codes:P0068, P0122, and P0223. This time I waited 5 mins and the car fired right back up and drove fine the rest of the way.
So it's the car acting like a dead battery one min, and coming back on line a few mins more that make me thing grounding issue. I'm not dumb when it comes to electric, but then I'm no pro either.
Thoughts?
