2001 Nissan Pathfinder Question: what does the code 1320 stand for on my nissan
P1320 relate to coil signal problem. P0505 is a erractic idle (probaly because you have an ignition misfire issue. P0300 is a ramdom missfire detected. Coils are a commom failure on that car and you need to be careful that you use OE brand of spark plugs

is it better to replace all 6 or just the ones that are misfireing

The cost may dictate that decision. Each coil has a retail price of $100+. A technician should be able to identify which one or ones that are causing problem.
