If you got an individual cyl # (p0302) to go with p1320 consider yourself one lucky person. Typically when p1320 sets it comes with a p0300, random misfire, code. Nissan recommends replacing all 6 ignition coils with updated ones. Since yours gave you the p0302 I might be inclined to try just the coil for that cylinder. I would highly suggest putting new plugs in as well.
