Default Rough idle

Upon cold start up as I sit in garage it will
Idle between 600-700 fluctuating a good amount in between there and causing te car to shake and vibrate some. More that I would think. Anyone else experiencing this ??

I can't say whether that's normal, but I hope it is. I would be happy with what you have described.

Yep, a pretty common question concerning the LS3 over in the C6 Forum. 430-436 HP and now 455-460 HP should have an ever-so-slight rumble at idle.
