Problem... Engine misfire on a brand new Vette?
Alright.
2003 'Vette, 1SC Package (the AE). 1100 miles or so on it since ... well, 1100 miles put on it since we got it about six months ago. Automatic.
Anyway, I start it up about ten minutes ago, and it's idling rough. ROUGH. Move a bit, CEL comes on. Check for codes, get this:
10 PCM - P0300 C
(Looked it up - Engine Misfire, and the C was something about MIC, although I'm not sure what that was.)
Five minutes later, it was fine. Running okay. Was fine during and after a hard lap around the block.
If it matters, it has just finished raining, and obviously, the car doesn't get much driving time - 1123 miles or whatever in a half a year.
What the hell was that all about?

Make sure your plug wires are on good and tight. Besides that, I'd bring it to the dealer since it sounds like your still under warranty.

Dirty or leaking injector? Water/crud in fuel? Moisture in engine compartment? Just drive it and keep an eye on it; chances are it won't return. :)
