Hi - have a 2021 burban with the 3.0. Truck has 6000 miles on it. Has been in the dealer for multiple check engine and emission systems issues. Those ha e been corrected with connector replacements.
since the first check engine it has been stuttering when accelerating. It feels like a fish tugging on a line.
we live at 8300’ and it seems to happen most when the car initially starts cold. Took it to dealer and they did ecm and tcm updates but it’s still happening.
anybody have anything like this?
