P0302 2005 Nissan Altima Sedan -

Question

So originally it was reading PO302 cylinder 1 misfire detected. So I checked the spark plug which seemed ok. So I decided to swap EA Coil between 1 and 2, to see if the error code would say cylinder 2 misfire. (thinking coil might need to be replaced) and sure enough. It now says PO302 cylinder 2 misfire detected. So safe to assume coil needs to be replaced? Not sure how to ck for air leaks. I've already replaced both cam and crank shaft sensors, which the first code told me was defaulting.

Answer 1

if you swap the ignition coil and the code changed, the ignition coil is bad.
