Rough idle
I recently purchased a new to me 2008 Coupe LS3 w/ Auto. I attended the Corvette Expo in Pigeon Forge yesterday. I’ve noticed a very minor rough idle. So I put my scanner on it and the rom fluctuates between 585-627. No codes present.
Does anyone have any idea where to start? Maybe a coil pack? Are is it something as as big as the ECM?

I think the rough idle is kinda cool.
Most hot cars have that.
If you get a chance try sitting in an old muscle car like a 389 tri carb '64 GTO or a '70 Hemi Cuda.
