Idle off a little in very low mileage truck

[Steve Paulus]

I have a 2016 Sierra 1500 with 6 cylinder. Only has 6000 miles on it. Truck runs great down the road but The idle is slightly off in park and in drive. No codes showing, anyone have this problem before ?   Thank you...

I've seen some folks come on the forums and talk about it, usually because the low idle causes a slight miss or stumble that bothers them.  A good tuner will raise the idle slightly and eliminate that.  Often, cleaning the throttle body resolves it on older cars getting on up in age.
