Does it do it only when your in drive? Like at a stop light?

Yes only when is on drive more commonly when I come to a stop .it feels like a small miss fire .

And in park it's fine?

If so, about every Tahoe with the 5.3 I've driven does that. I did plugs and wires on my wifes and it helped a bunch. Numerous posts about the issue. Its aggravating if its the same issue, but dont think it's an issue. My buddy brought his brand new Tahoe to the deal 3 times for it, they finally told him it was normal, confirmed by driving two more new Tahoe's. My buddies 15 1500 PU does it also.

Are there any dash lights on? If it’s AFM you’ll notice it when stopped. Look in your owners manual to see what it says. If it feels like a new problem that’s different. The dealer should have told you right away if that’s what you’re feeling though. The ones I’ve driven feel like you’re holding a fishing pole and something is nibbling at your bait. Kind of a bump bump then it goes away when you take off
