Idling Rough 2016

[Stacie0522]

Does anyone have a problem with their Tahoe idling rough at stops? I have taken it to several shops and they tell me it is because it is a flex fuel and it goes to 4 cylinders. I don't buy that because it didn't do it for the 1st 8K miles. The put motor mounts on it hoping that would help but it did not. Any thoughts would be appreciated.

My 2016 does the same, dealer gave me double talk that it's nothing

On my 2016 the rough idle comes and goes but not enough to make me complain to the dealer..Every vehicle I have owned [since my 1967 Impala] has done this...I generally find using Exxon-Mobil 87 regular makes it idle the smoothest.
