rmk614 Posted July 15, 2018 Share Posted July 15, 2018 Hey! I'm new to the forum, as well as Subaru ownership. As my profile says, I have the worst luck in the world with cars, but I try. I'd been told "buy a Subaru. They're super-reliable!", so I did. It made it less than 6 months before having big problems including stranding my family and me in WV on the way home from FL. I'm not a mechanic, but try to do as much as I can myself, as I really have car problems enough to keep me from ever being able to afford my car problems. Recently, my 2008 Outback 2.5L SOHC started misfiring. I went to Advance Auto Parts and had them pull the codes. It had P0102, P0113, P0303, and P0301. I found out the P0113 and P0102 were about the MAF sensor, so I picked up some cleaner and cleaned it, and I replaced the spark plugs. It was still misfiring, but it seems to be just on cylinder 3 now. I went to a mechanic friend who hooked it up for full diagnostics, checked for sparks on all four plug wires/coils, and, after showing consistent misfires on cylinder 3, gave me his best advice, which was to replace the coil pack. I replaced it, and it's still misfiring. He advised that the bad coil may have burnt the plug out, so I tried replacing those again, as well as the wires. Still misfiring. When the plug from cylinder 3 was removed, it smelled heavily of gas and showed no blackening from ignition that the other 3 are showing. So, after replacing the coil pack, spark plug wires, and plugs, I still have a consistent misfire on 3. Does anyone have any thoughts on what could be going on with this?

rmk614 Posted July 15, 2018 Author Share Posted July 15, 2018 I forgot to mention: I've tried disconnecting the MAF, and it doesn't get the car running any better. Is there some sort of trick to how that has to be executed? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted July 26, 2018 Share Posted July 26, 2018 Do a compression test. Quote Link to comment Share on other sites More sharing options...
ebarb Posted July 31, 2018 Share Posted July 31, 2018 ^ sounds like the worse version of what I've had for a while in my 05 outback and know to be low compression in cyl 3. Quote Link to comment Share on other sites More sharing options...
