I have 2005 g35x sedan with random po300 misfire. Car drives perfectly drive and idles great. Would spark plug or ignition coils still be the problem even if drives normal? Any recommendations please would help

i have ave to change the topic now. I fixed the misfire which was a crack on the stock intake. Now I have a p1273 and p1283 which are the air fuel sensors on both cats I replaced those last month. But I’m reading now that it needs a relearn when you replace those air fuel sensors
