Default Code P0302 misfire #2

Hi guys,

I have just ran into a problem with the cel code P0302, apparently it has to do with a misfire. The check engine light comes on and then the car would make sparking/popping sounds during acceleration, sometimes resembling something exploding..
It would drive "normal" but with the engine light on. Any idea how myself or any shops will be able to fix this? or Will I have to visit the dealer?
Thanks.

Check spark plugs/change them.

Check spark plug wires.

Check coil packs.

Swap coil packs between #2 and #4. See if the code goes to cylinder 4. If it does most likely the coil pack.

Could be injector problem as well.

If you aren't too mechanically inclined I'd probably take it to a subaru tech. That doesn't mean you have to take it to the dealer though.

PM 5 Zigen??
