I had this problem in my 2001 QX4. I fixed the problem by replacing all 6 coils and plugs. Good luck

Ignition signal primary circuit fault. Good luck.

I have been running a P0300 random cylinder misfire and P1320 for a while now, I have done a lot of research and like stated above it always points back to ignition coils.

You can get a set of 6 for $220 shipped on Ebay, install yourself or pay for the labor, will be a lot cheaper.
