I tested my car with an Actron cp9125. The code I got back was P0304. The computer said that code # means my #4 cylinder Is misfireing. My question to you Is, do you have any sugestions on how to troubleshoot the problem or possibly fix the problen? Thank You Very Much! A very happy subaru owner. Could please send an E-mail back to me to. Steelermania7@verizon.

First thing to do is to switch spark plug, plug wire and if acclipable coil/coil pack with another cylinder, say #1 reset code and drive away. Does vehicle continue to show code on #4 or does it switch to missfire on 1 or po301
