Even the cam in the L99 makes it shake a little at idle, although I'm sure to much less extent than the LS3.

Get that car to a dyno. Maybe its not stock after all.

Nevermind, just realized the video you posted isn't of your car.

I should just go on record to say:

Although this is not a vid of my car, mine has the EXACT same type of 'bounce' as seen here. Granted by the sounds of it, this one would appear to have a CAM ?

Mine has only a K&N CAI and Solo-Performance Axleback. This bounce was present prior to the installation of these items, so I doubt it was either of them. I guess then, this is not a normal attribute of this car/ motor with the rest of you ?

Runs fine ... Mines not that loud either as this one from youtube I found seems to have a cam installed.

I just wasn't too sure as no other car that I have owned, driven or rode in has done this. It's very new to me. lol

Why is the gas gauge positioned where it is? Shouldn't it be at the bottom right corner?

Looks like somethings off. Mine sits as still as a corpse while I'm idling.

Perhaps unplug your battery and reset the car as a first step to troubleshooting? Just see if it doesnt reset your fuel/air numbers.

Hmm, I might try that ...

My tach needle bumps around while at idle and at highway speeds. It bobs around like its floating on water. Very slight movement, but its noticeable
