Nissan Repair: P1320 and P0301 for 2001 Nissan Pathfinder, spark plug wire, right cylinder

Question
I've had one coil go out(Coil 1 after receiving this engine code free from Autozone)and to my understanding Coil 1 is different from the other 5 Coils.  How do you "pinpoint" the Coil that actully went out?  Also P0301 engine code; what does this code allude or does this code essentially means the same as the P1320 Code?  In other words Autozone's diagnostics resulted in these two codes?

Answer
Hi Keith -

Code P1320 is an intermittent no pulse in the ignition module circuit. This will probably go away once the coil is replaced.

Each cylinder has its own coil, and since P0301 is #1 cylinder, it chould be attched to the spark plug wire to that cylinder. Numbers on the distributor cap should direct you to the right cylinder if you get lost.

Hope this helps -
