I'm driving a 2001 Outback wagon with the 2.5 motor and I seem to be getting a random CEL that decodes as a P0304 cyl #4 misfire. I am in the process of clearing it and letting it pop back up to try and identify a pattern but at this point I am kind of stumped. I don't notice an actual misfire while driving, the light just sort of shows up from time to time. I have new plugs and wires and I tried testing the resistance on the coil, secondary was 13.6k on both, I wasn't able to get any reading on any of the pins where the 4-pin wire plugs in.
Last time I cleared the code I drove probably 30 miles, mix of highway and in town before it came on.
I've done some research on this but the causes seem to be all over the board. Since I don't actually feel anything happen to the engine when the code shows up I'm hoping you good people here may have a suggestion or two for things I can look into. In the meanwhile I'll be trying to log when and where the code shows up and I have purchased Torque for my Android and a BT adapter for monitoring the engine while I drive.
Thanks for your time,
