Any thoughts? Do need to change out all of the coils b/c of the 1320 code or is there something else in the ignition system that could be causing the problem?

I would change the rest of the coils or you could get 2 and try swapping 1 front and 1 rear coil at a time to see if you can figure out which one is causing it.
