Hello Scotty. I am a longtime follower with a 2010 Dodge Caravan with a 4.0 and 6 speed auto that has 240k on the clock. It recently started misfiring so I ran the codes with a snap on scanner (P0300, p0304 and p0306). Here is what I replaced in order: spark plugs, coils, injectors, fuel pump and computer. It still misses but switches from cylinder 4 to 6 and then back again. I think my van is possessed! Please help.
Doug
I just test drove it with the scanner and it smooths out at increased rpms.

Swap the coils from cylinder 1 with cylinder 4. See if your misfire stays on 4 or moves to one. Did you do do the plugs yourself? If so did you use a gap guage or just toss them in?
