Missfire

[PaPa22Streetglide]

Too start off with Good afternoon thanks for allowing me to join this group. Maybe some of you can help me I have a 2022 Ram Laramie it has 5000 miles on it. I bought new October of last year. Over the past few months I have been noticing when I go to start my truck. It's got a hesitation Like a misfire and then sometimes it backfires through the air box. Has this happened to anyone else if so how did you all fix it. It has been at the dealership for 2 weeks and they just called me and said they can't find anything wrong with it. It's really aggravating.

My 202 1500 classic has always had a stumble/hesataion at cold start . Dealer could not find it niether . I just let it run for a bit and expect it not to respond at the throttle until it warms . by then its fine . No difference between summer or winter . Many persons on the forum say its a normal Hemi thing , But backfiring is a concern tho mine fortunately does not do that
