i feel like at this point it has to be the only reason. so many of the cars symptoms didnt exist before the dod delete kit was done. what else could make it random misfire at this point? any ideas what it could be?The DOD cam has a different profile on the lobes that shut down due to the difference in lifters. If the lifters they put in were not DOD lifters (and why would you when doing the delete?) then you have 4 cylinders getting more valve lift than the others.
Is it enough to matter. I don't know lol.
