Hi guys I'm new here, i got a ?...
just got a 2013 Tahoe z71 4x4. it runs great...has one issue, small idle vibrations at every red light or stop light. Currently using E85 gas , Im thinking of adding seafoam to gas. it should get rid of the idle vibration right?. is that a good idea even it says do not use additive with E85 or should i put some seafoam next fill up of regular unleaded gas? what's the best approach?

Is this your first NNBS 5.3? If so, many of us have had the same exact complaint/issue since new. These motors stumble a little at idle during extended stops. Don't know of a fix.

Seafoam can help, Clean the throttle body, MAF sensor but like Euro Driver said it will still vibrate but that will help stop a lot of it!

In an AFM 5.3 you won't get rid of all the vibration. Just the nature of the motor. Seafoam will help though.
