I have been driving the truck for 1 year now like this hoping it would work it self out but it has not. I am fixing to just dump the truck and never look back.
What tuner you got? Try a misfire monitor neutral profile correction relearn. Any time there is major engine work, this should be performed. Dealer should have done it after the engine replacement, but you never know. You need an x4 or livewire to do it
