P0302 2005 Mazda 6

Question

Just purchased a 2005 Mazda 6. Not even 24 hours have passed since I gained ownership of the car, and the check engine light came on. Got a P0302 code, cylinder 2 misfiring (thanks advance auto parts). What could cause this?

Hi there

Usually a code like this is a simple ignition coil or spark plug issue. It can be a larger issue like a fuel injector or intake manifold leak, but generally the place to start is with the ignition system.
