Ok update... so dealership thinks I have a bad ECM? Yesterday the truck started losing power would go above 55 but then would kick in and go but that is a symptom of the EGr Valve which the screen on my truck is showing a leaking EGR Valve. I don’t have any symptoms of a bad ECM that I can tell... thoughts.
