Raise your hand if you ever-so-slightly enjoyed reading about a first time inlet replacement

Move the injector to a different cylinder and pray the misfire moves. If it doesn't move then sell the car or prepare to face years of fighting. Refer to the misfire link in my sig for deets.

Replace the doors and keep the old girl out on the road where she belongs.

I designed / printed an LGT badge a few years ago and i still like it more than the few other designs I've seen floating around. I'd be down for making a few for you if you're still looking for options. I'm not against sharing the file if anybody wants to PM me. Both attached images are of the same file, just slightly different views. Crappy pic of it on my car: https://www.instagram.com/p/BDrnGGAmqj9/ Regardless of who you get a badge from: I'd suggest black ABS for the background and red ABS for the raised letters.

Muy bueno!

The correct way to handle this situation is to only talk to your wife about your car issues if and when she asks. Be honest with her and don't lie, but be careful to only give her direct answers that give her confidence in your ability to address these regular maintenance issues that come with turbo Subarus. The single worst phrase I've learned to avoid at all costs is "I think this should be the last thing for a while".

Wow, good job finding that leak. Hopefully it's your only one.

Do it. There's a big cars and coffee event here in N.Ky on Saturday mornings that's fun to check out, and there's a large Subaru meet late in the summer.

Almost no misfires on the way to work this morning. Car season is approaching and the itch to solve the mystery is growing again. On a positive note: BtSsm via heiche's BT dongle is 1000x more convenient than using a tactrix and usb cable every day. I should have bought one a long time ago.

I really hope your issue is gone and never comes back. I'll be able to drive my misfire-mobile happily knowing that you're running smoothly. Yep, I'm learning how to become satisfied by driving vicariously through Internet people.

I also saw scratches inside my cylinder, but the piston was later confirmed to have zero cracks. So don't freak out if you see minor scratches.

I'm all about jumping to conclusions and spending money based on assumptions (see my build thread), but let's not blame Shell just yet. Remember, the single thing that protects our cars from certain destruction comes from Shell... the almighty Rotella 5w-40. It could have been a chunk 'o gunk that was floating around in there from another fill up.

Sounds reasonable to think that a large enough piece of gunk stuck in the line (pre-fuel rail) might have an affect on the fuel flow going to both injectors. The likelihood of that being the problem seems highly unlikely so don't take this as my suggestion to tear apart a fuel rail

interesting

In boost I'm pretty much always at zero misfires. If I don't see misfires at idle + 0 mph my palms get sweaty and my fingertips get numb.

Four kids, huh... our situations get more and more similar. We've got 5. It brings a smile to my face every time Yes, but lately it'll occasionally move to a different cylinder. It generally sticks to one cylinder at a time, but in the last few months I've seen #4 occasionally acting like #2 did way back when I started my journey. It's encouraging to finally see that something is changing, maybe even because of something I did on purpose. BtSsm is the shiznit. Disabling the CEL for misfires is exactly that easy. I think I remember five codes. One for each cylinder and one for a random/general misfire problem.

Time to disable the misfire CEL. If you're opensource (tactrix) we can help if you need it.

Great, mostly, but sometimes no, although yes actually. Thanks for asking. Right now it has/feels like it has a boost leak somewhere and I'm waiting on warmer/dry weather to try out my new smoke tester (party fog machine). It's been super funky in boost since I replaced the FPR, so I'm assuming it's a boost leak.

Welcome to the nightmare. In a sick kind of way I'm glad you're here. :spin::spin: Have you starting counting how many times you've said "Ah ha! This has to be it!" As Mr. ValveLash already said, it's not very difficult and tots worth a shot. It's also fairly inexpensive compared to... rebuilding the motor only to discover the misfires DON'T GO AWAY. I'm still a little salty about that fun little exercise. That's my favorite too! Maybe our two cars are dopple gangers. In all seriousness, your symptoms sound incredibly similar to mine. There's no real pattern, except sometimes, but then not really, but maybe yes, or no. How many components need replaced before the root cause is discovered? I don't feel like I have a whole lot to contribute anymore because my personal experience has convinced me that my misfires may never go away no matter what I do. They might even be a figment of my ECU's imagination (I'm partially serious... and my ECU will probably get replaced in 2019.)

Perfect timing as I'm revisiting the (total crap) design and execution of my diy smoker.

Glad to hear you found the cause. Sure is an expensive way to find a blown fuse.

I can confirm that oil (or fuel) pressure can be logged via a deleted TGV as long as you use a pressure transducer with an output of 0-5 volts. That's also the correct location to put the oil pressure sensor (transducer).

Disconnected vacuum line somewhere?

I replaced the stock FPR this weekend. The idle is still rough and the misfires are still there... but now in cylinders 2 and 3. Technically that's a change so I'm all smiles. **see edit from 01-OCT-2018** After I put on the sti fpr I reset the ECU and let the car idle for about 10 minutes, and then I rev'd the motor like a maniac about 10 times because I want the neighborhood to know that I'm a badass and I work on my cars. After I turned off the motor I noticed a small amount of sweet-smelling smoke coming from near the turbo. Thinking I had a coolant leak to track down I got down and looked under the car. Much to my wonderment the smoke was coming from the rear (3rd) cat. It seems unlikely that coolant would get that far back before dripping onto the exhaust. Now the motor stumbles really, really badly at mid/high RPMs. It only stumbles under load while driving (rev's fine all the way to high heaven when parked in a driveway), and it feels like a cat might be clogged. I'm concerning enough that I'm going to keep the car parked until I can take off the pipe and take a peek. To be safe I'll probably get out my auger bit and go to town on the cat. Kind of ironic that my Ryobi drill is green. ***01-OCT-2018 edit**** One of the fuel lines was loose/cracked and leaking fuel. I figured this out before the car blew up, but not before getting stranded on the side of the road in the middle of the night. Fuel line replaced, user-generated stumble gone, misfires still present.

^ that's a good way to explain the problem.
