I can totally buy that. Still, incredibly weird I was only getting a misfire on 5, until I swapped the 1 & 3 coils and then got "misfires" on 1, 3, and 5. Then, swapped the 1 & 3 back and continued to get misfires on 1, 3, and 5. And even more so when going with all new coils and continuing to get misfires on 1, 3, and 5. I could understand a DISA issue or vacuum leak generating all those codes. But why now, and not before I swapped up the 1 & 3 coils?? Makes no dang sense.
