I have a 2011 Avalanche with 18000 miles and have the rough idle at stops as others have mention (no service codes). The question I have is while driving in city conditions 0-35 mph with stops, when the AFM shifts downs from 8 to 4 the entire ride of the vehicle changes as in not as smooth when using 8 cylinders. It seems like it really struggles while in the 4 cylinders during city driving.
Anybody in the club have the same? Maybe it's me, but I sure didn't notice it when I bought it new with 5100 miles!
