Took my brand new 5BW out for a mildly spirited drive last night, CEL comes on 5 minutes before home. This morning I call OnStar, they say it's code P0300 - emissions equipment malfunction and recommend service within 7 days.
I figure this is either nothing to worry about best case, or worst case the engine is missing and dumping unburned fuel into the cat and causing a code. The engine idles nice and smooth. Way smoother than the LS3 in my SS Sedan did. Power delivery is smooth, immediate, and unmerciful just as I would expect. Oil level and appearance are ok. Car has less than 800 miles on it.
Obviously I'm calling the dealer tomorrow, but it's Sunday and my anxiety is getting the best of me. Does anyone have any insight?
