Is C7 designed to shake a little while idling?

Picked up my first C7 in November. The car shakes, light vibration when it idles. Does it when cold or at operating temperature. The tach stays rate on 600RPM at idle and runs flawlessly besides this. I took it to the dealer a couple days ago for the 500 mile oil change and asked them about it. They put a scanner on it to check for codes but there were none. They didn't seem concerned at all. Is this normal?

When I drive my wife's Acura RDX, I sometiimes exit the vehicle with the engine running (and get crap from my wife for doing so): no vibration with the engine on or off vs. my C7.

I would know nothing about my car if it wasn't for this forum. I heard it today and I don't think I've ever noticed it before. Had it less than a month. I was thinking, what in the **** is that noise? Minor, but there. Now I know.

I have found that to be completely normal of my C7 too. Shake @ idle. I'm also finding a slight falling on it's face before rocketing in acceleration when anywheres near cold after start up. All of my turbocharged diesels over 30 years have had a very smooth idle with no vibration. Somewhat odd that the LT1 shakes at idle, but it does.

Most modern engines run really smooth, when I first got this C7 I also thought it was misfiring at idle. The cam isnt that radical for a 6.2 liter, I think the slight roughness is designed in.

Yes it is normal. Has been happening for a while - all three of my C5s did it.

When I bought my C6 I had it inspected by the dealer but never drove it. Once I drove it I was terrified I got screwed because it was shaking at idle, as I had never been in another Corvette. After getting used to the car, and riding in other Vettes, I now know it's normal. C7 does the same thing. I imagine it's a characteristic of a high HP pushrod V8?

This post must be a joke. A sports car “shakes a little”. Geez. Buy a Cadillac or Mercedes.

It's not from a "hot" cam. My C6 Z06 has more displacement and a "hotter" cam and more horsepower than the LT1 and has no vibration at idle.
