Default Cylinder #2 Misfire + Running Like Crap

hey guys,

I ran into a problem yesterday. Coming home from work, I overestimated it seems, how much gas I had in my tank (I usually go by mileage and I thought I had enough.. but I guess being the winter season has compromised my Fuel Economy). Fuel light usually goes on way early, but I guess this time it was accurate. Strange though, bc the needle wasn't even on E In any case, engine started bogging, check engine light came on + loss of power so I pulled over. Checked everything... figured it was just low on gas. Still started up no problem, just running like *****...so tried to limp it to the nearest gas station. Needless to say, I didn't make it. I decided to pull over/park early on vs having it die on me in the middle of the street. Had my pops pick me up with the gascan, filled it up with 4 gallons or so of premium then took it back to my car for fueling. Started her up and she still ran like ****, better than before but still bogging + loss of power. Could hear intermittent knock + misfiring + blinking check engine light. Engine oil level was at half so I added a quart of 5W30 synthetic. Sucks that I was in the middle of nowhere + the local gas station only had some no name brand . Usually use Pennzoil Synthetic. 200 miles away from my next oil change (3k mark). Managed to limp the car home & pulled the codes with my Accessport.

P0320 - Cylinder #2 Misfire
PFFFF -misc cobb error code
PFFFE -misc cobb error code

so cleared the codes to see if that would help... still running like ***** and clearly there's a misfire. No CEL atm probably bc I haven't ran the car since I cleared the codes.

I'm thinking since I ran low on fuel, probably picked up the sludgey goodness at the bottom of the tank + ran lean = fouled plugs , clogged injector, or maybe just a bad coilpack. I read up on a few things and ppl said I should swap coilpacks to see if the code follows the coilpack. Idk how to do that . & same with the fouled plugs. I've never touched the plugs on this car (not familiar with the boxer motor... have only dealt with inline 4's & 6's in my mechanical history). Is Plug #2 the hard one to get to? They were changed about 15k miles ago when I got my 60k service done (at 77k ). And in terms of the injectors.. guess I wouldn't know unless I got them flow tested / checked. Hopefully it's something easy to fix... the one thing that concerns me is this intermittent "tapping" or clicking coming from the driver's side front of the motor.. like behind the timing belt cover. Very intermittent, not continuous either at idle or under throttle. It's possible it was there before and i never noticed it but i definitely notice it now. Engine shakes a lot now with the misfire so idk if that's a contributing factor. Hope to God it's not a timing issue.

In any case, any input would be greatly appreciated. This is the first "major" problem i've ever had with the car since I've owned it. Hopefully it'll be a simple enough fix.

thanks for your time everyone!!

#2 is the cylinder on the pass side so easiest way t the plugs and coils is pull off the intake and its right there. Try swapping coils then plugs and you can swap the injectors too instead of sending them out to be cleaned

When you pull the plug, do a compression check. Put some Lucas gas treatment in and see if it helps. Try the simple stuff first.

Your right I was mistaken. Then the easy way to get to those is pulling the battery and washer tank if you ha a top washer tank. Sometime you can even get away with undoing the battery tie downs and moving the battery over to get room

thanks for the input guys.. hope to God it's not a cracked ringland.

took a vid of the tapping sound I was talking about. Did the oil cap test.. no smoke.. just air or smokeless exhaust coming out.

You can pull that small section of the timing cover off... just a few 10mm bolts. I'd pull it and check the tensioners, belt, and other stuff in their. I am unsure how this could have started due to running low on gas though

^beats the hell outta me.

also i just noticed that my ABS + BRAKE light started blinking simultaneously every 30sec-1min or so

never had any problems w my brakes before... is that an indicator of some sort?

codes finally came back after i reset my ECU. same 3 codes. I haven't done anything physically to the engine yet so it's to be expected.

1 Pull spark plug and check it/replace it.
2 Swap coilpacks.
3 Swap injectors.
Do step one then check, etc...

If you aren't comfortable doing any of that just take it to someone with Subaru knowledge.

This. Car could have jumped timing...doesn't really sound like rod knock. My guess is ignition/timing related.

bump for the possibility that Coil #2 (located around where the noise is coming from) has gotten loose and is wobbling around due to the misfire (possible arcing of Coil #2) . will investigate further when i get a chance to take it out / swap it with coil #4

I had a very similar problem in my 2005 sti. I ended up clogging my fuel injectors and just cleared the codes and added a can of cleaner to the gas tank. Now she runs great.

I know this is a bit of a necropost, but i'm currently going through the same thing minus the clicking noise your getting. I pretty much just did what Badler suggested and started code chasing. After using a fuel system cleaner, i noticed the problem was less persistent, but i was still throwing CEL's for misfire in cyl. 2. The next day i swapped cyl. 2 fuel injector with cyl. 4 and threw no CEL (possibly because of the cleaner), but I took a look at my cylinder roughness on my COBB access-port and noticed that the roughness went from cyl. 2 to cyl. 4, when the day before it was on cylinder 2. So that to me is a fuel injector problem, sent it off to deatschwerk to get it cleaned out using their dynamic service option. Still awaiting the return of the injector to see if that was the problem. As soon as i get it back and get the injector back in, i'll post the results (that is if you haven't already fixed the problem). I hope this helps you out even a little bit.

Good you figured it out, ended up being a clogged injector for me, deatschwerks did an awesome job on the cleaning/rebuild.

Isn't the code for cylinder 2 misfire P0302 not P0320? P0320 is something different altogether. Regardless glad you fixed it. Misfires are PITA to fix...

Glad to hear you got it resolved - I had this happen on cylinder 3, one week after buying my 06 STI. Check the plugs while you are at it - mine had a gap about 3x the spec.

These kind of statements without asking any more information from the OP just pisses newbies like me and might be a nightmare for the OP. Just jumping to the conclusion is not a good idea so please give some troubleshooting guides like other members did to the OP. So happy for the OP that he was able to post a VID and with the help of some other members he was able to resolve it. Congrats and bump from me :--)

I agree 100%. Jumping to the worst scenario helps no one.

Yep. The. "OMG ringland rod bearing head gasket" guys get annoying, especially when they know nothing about the car at all. The place is infested.
