My 2018 Atlas S AWD 3.6l, kept dying so I replaced the battery Sunday, Monday it started misfiring, Tuesday it was misfiring and check engine light came on so I had the codes ran - code came as cylinder 6 misfire so I had my spark plugs replaced. Right after I picked it up, I could still feel the misfire so I took it back and it is pulling the same code. They moved the coils around to test them and they are fine… anyone had a similar experience? What was the final diagnosis?
