I did some searching through the forum and on Google as well. And while i found allot of sort of similar questions, mine has some subtleties so i figured i would post it up and see what you guys think.
2020 2500- just rolled about 51,000 miles. For about 6-8 weeks now i am getting a slight idle surge. especially when cold as we are not seeing some temps in the 20s. The truck is tuned from Calibrated Power. I generally keep it in the street setting, and now that i am typing this i should maybe put it back to modified stock for a few days and monitor. I am also due for fuel filter service again. In addition, i have not had the most recent DEF recall performed because i was to lazy to pull the tunes last time i went in for an oil change. When i had the tune done, i did call into the dealer because the tuner needed to now if the lift pump replacement had been done, the service manager told me it had. Short of that the truck runs and drives great. the surging when cold or at idle isnt even enough to bump the tach. but i can hear and feel it.
I am answering a few of my own questions as i type this out. I should get the filters and DEF recall done and probably see how that does. Just wondering if anyone has witnessed a surge this slight and sorted it out?
