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?

What was used to shut off AFM? Dongle? ECM tune?
I should also note he shut it off on my 17 Silverado and never had a problem but this is the second time we’ve tried with the suburban. The first time he couldn’t get his computer to talk to it and afterwards the power steering and stibilatrack started to act up and I just unhooked the battery for 15 minutes to solve all of that so that why I’m kinda leaning to my computer needs reflashed

When you remove the dongle, does the issue go away?
