New code for me today. Started up and she sputtered/misfired. Code thrown P0304, misfire cylinder 4 I guess. I cleared it. What caused this? Voltage issue? Mixture? Timing? How do I cure??

 

Most likly cause is a bad plug, wire, cap, orrotor. Basicly needs a tune up. These are the most common things, but it could be something else, like a vacuum leak, injector, or low compression.
