P1320 code on 2001 Pathfinder

[gosmithpa]

Trying to resolve P1320 code diagnosed by dealer. Claims misfire but cannot determine which cylinder. Reset twice. Waiting to happen again to see if cylinder sets itself. Is this being diagnosed properly? Any suggestions on how to resolve this without paying big $$. Have had many sensor issues with this Pathfinder but no major mechanical problems yet. 65,000 + miles on 2001. Dealer also recommended replacing all coils in lieu of identifying which cylinder may be causing misfire. Also recommended keeping vehicle to drive until problem happehns with scanner installed. Seems too time consuming for me if in fact it happens again. Any suggestions? Is this be diagnosed properly?

1320 code is for ignition primary circuit. i have seen a lot of maximas get this and need a set of coils. sadly that is the typical repair.
