p1320,p0300

Question

I have 2 codes on my 2001 Nissan Maxima, P1320, and P0300. I had previously changed all the ignition coils, but they weren't brand new. but the engine lights goes off by itself for a few days then comes back. car also misses & trembles while driving and a lot while idle

Answer 1

HI there

The factory repair is to replace all 6 ignition coils. This is needed because the computer cannot tell which coil is misfiring, and because it takes specific conditions for the coils to actually misfire. Putting used coils in can cause problems because you have no way to be 100% sure they are good.
