New here and don’t know if it’s been discussed but I had the active fuel management shut off on my wife’s 18 suburban. Now getting a p16f3 code and it goes into limp mode and shuts off. Can clear the code with my reader and it fires back up and drives for a while then comes back. Also noticed it has a stubble on acceleration in 2nd gear and that’s usually when it shuts down. Been reading that that code usually leads to the ecm being reprogrammed. Anyone have any insight or experience with this?
