Subaru Misfire Repair | How To Fix With One Tool Only!

[@paul48]

I have been doing my own work on cars for a few year now, but I was still able to learn a lot from this video. Very good information, and well presented.

[@CarsNToys]

Great to hear!

[@Nickdeltone]

Great video. The spark plug wire test should be reading in the kilo ohm range. The wire you tested showed 5.21 k ohms or 5210 ohms.

[@lawxr6eBay]

Make sure to wear insulated gloves or carefully inspect the boots for splits/cracks First before Pulling on it Live- with vehicle Off. Pull on a Hot One that's cracked while it's running and get Cracked! Lol great help for simple diagnosis, Thanks!

[@robtaft9139]

I just learned this the hard way...1" arc

[@doranvee5944]

Superb teaching video. I have never used a multimeter, but you going through step by step makes me think I can do it. Thank you so much!

[@drake.debars]

Fantastic video! A lot of people can benefit from this. I’m glad I clicked on the first recommended instead of scrolling down like usual

[@jesseullberg4217]

Great straight forward video and not just scatter gunning parts at things.

[@rrpawluk2]

Thank you - very informative with so many ways to test. Would have been neat to check one other quick home test for wires, specifically if wire casing is damaged causing short. At dusk or in dark garage spray fine mist water on wires with car idling. It the wire is shorting or arching should see a spark at wire itself and/or a dip in rpms. Not sure how reliable but you def had a bad wire so would have been neat to see if shorting was obvious. Also good check if P0304 code seems to correspond with rainy weather.

[@harlankraft578]

Thanks was checking the injector with a screwdriver and found was only a loose plug wire! Thanks for sharing the tips and tricks!!

[@Mrjonblakely]

You said 11 ohms @14:40 on the coil, I think you meant 11k ohms. Thanks for your video.

[@o.c.stiggs5377]

Thanks for an exceptionally well-done and useful video.

[@crazyDIYguy]

I love the ej253 intake manifolds. Not crazy about the newer black plastic ones.😐

[@jp5617]

My lucky day - just discovered your channel and have the same suby so will enjoy doing new stuff in addition to what I already did. In terms of design this is one of my favorite imprezas. I think this gen design is underrated for some reason. Glad there are people like you there appreciating them and keeping them in good shape. Mine is in France gen 3 R 2.0l model - having a big trouble finding ignition coils for some reason. Do you think that coils for 2.5 engine would fit on mine as they look exactly the same. I presume yours is more powerful model there in USA. In any case thank you very much for sharing your skills.

[@slack757]

What a great video. The video is well done, easy to understand and very easy to follow. You pretty much cover everything one would get on a misfire.Thank you for saving a ton of time.

[@yachtwork]

Really good how-to video. thanks for posting. Nice work.

[@stephenhurd1489]

I'm sure u meant well but what about the shock from the plug wire when the engine is running!

[@kb1qzh]

Wish I saw this last year (P0301 and P0302}I've already gone through coil/wire/plug replacement with the dealer. I have my Fix at a Subir shop for a second opinion. The current thought is the fuel pump.

[@kinyosidennis4103]

i leaned a lot from the video thanks dude

[@LB-ge9yz]

I have the exact same Subaru and I also had my first engine blow a head gasket, destroying the engine. I put in a new remanufactured engine with better head gaskets and replaced everything else with new as well. Everything has run great except for periodic cyl 3 and 4 misfire codes. I have yet to be able to find the cause for it. 80,000 miles later and I am still getting the cyl 3 and 4 misfire codes periodically. Not sure what else I can test or how to go about testing internal mechanical issues.

[@chadharris5072]

Spark plug tube seals leaking oil onto plugs and plug boots is a common reason for a subaru to misfire.

[@mintpatrol3319]

I may have just missed it but whats the bolt size for the metal plate covering the fuel injectors?

[@jacquelynlafevers8846]

Great video! Very informative. 💯

[@dfields9511]

Great video there , I recall some you did before on a Nissan Maxima. Do u still have that car ? If not what killed it Transmission, accident , engine etc

[@gomirlez]

Hello, mr subaru!!! I have a 2011 outback with 140.000 milles and I recently put a fluid injector cleaner in to the gas tank( i put half of bottle LUCAS BRAND) the next day my car started to shakes and loose power, also the check engine light turns on, the brake light is on, the cruise light is on and the vehicle dynamic control warning is on…. Some videos on KZbin says it could be the gas cup or the parking brake light switch….. I CHECK THIS ALREADY AND THE ARE GOOD…. Do you think the injector cleaner DAMAGED the ignition coil or the spark plug or the injector???? Thanks again for letting me know, i subscribed to your channel to watch all the videos you have… the will help hound people like me….

[@Socko00taco00]

Check engine light came on yesterday with a P0301 code. So does that mean I only have to worry about cylinder 1 or should I check the other ones as well? Also this was probably one of the most helpful car fix KZbin vids I’ve ever seen.

[@justinhalvorson7571]

Cylinder 1 is ur problem

[@jamesdodds3195]

I have a p0171 only, think it might be a spark plug or a vaccume leak near the cylinder?

[@aTROLLwithBlades]

Thanks man! Great video! And not annoying or in terrible quality! A very rare find on KZbin in this age of clickbait

[@yehtutnaung7164]

Thanks for sharing

[@TheeJudge]

This video was very helpfull thank you

[@Mark-ks9jj]

Very informative video thank you

[@valireklaam]

If the injectors are clicking consistently with the screwdriver test, then the ohm resistance test can still show other errors with the injectors, correct?

[@gbsk12]

I put new plugs wires and coil pack in and the injectors are good and I still get a P0301 reading What do I do now? It still does not run good when I get a load on it

[@Kradle]

Does polarity matter when connecting your multimeter to the injector? Thank you!

[@ButchBates-t2y]

Well said everything! Thanks!!!

[@traviswillis5559]

I’m looking a buying an 97 outback with a misfire. It’s got about 180k miles and it’s auto. How likely do you think it is to have blown a head gasket. The owner isn’t mechanically minded and they don’t know the engine light code, or if it uses water etc.

[@markdiffendal4202]

Does the code always tell you what cylinder? I have a 2011 Legacy 3.6R and my mechanic says the code just says cylinder, not which one

[@Blue_devil_209]

Dude great Video.

[@atypican]

Great video. Thank you.

[@MsTheGamingBro]

Really helped me out for my own Subaru thanks a lot, I have 4 codes coming out of my OBD2 and it's for cylinder 1&2 so I guess I need to work of that

[@christhomas7750]

Great video very informative!!!!

[@taurinediamond1069]

My 2004 Forrester XT is misfiring on all four cylinders at high RPMs. It'll throw 8 codes, each for each four cylinders twice. I've replaced the spark plugs and the fuel filter and I still can't find the problem. I was hoping maybe someone would have some input.

[@nelnutta1055]

I am having the same issue with a misfire P0301 Cylinder one. I did the beginning part and verify if there was something wrong with the motor unplugging the plug which it it changed the motor's idol So I believed it to be working correctly. I have tested everything you have stated and all seems in good working order. If your coil pack plug wire spark plug An injector is good What would be the next step if you're still getting A code for miss fire?

[@nelnutta1055]

My motor was also pulled out recently had head gaskets and a valve job that has all new plugs and wires.

[@Americansikkunt]

@@nelnutta1055 I’m in the exact same situation. What ended up causing the misfire? Fuel injectors? Burnt valve?

[@RIPdBOON]

Great video. I have an 04 Legacy with cylinder misfire on 1 & 2. I was warming up my car when the engine started to shake and the check engine light started flashing. I also noticed the Catalytic Converter was glowing red hot. Any idea what could be causing this?

[@nonenone6937]

You answered your own question

[@RIPdBOON]

@@nonenone6937 started with a tune up. Spark plugs and wires and ignition coil and she purrring again. Thanks tho 🤙

[@lauriergauthier5368]

you could have 2 spark plugs mixed up as well

[@RIPdBOON]

@@lauriergauthier5368 I just went ahead and replaced all spark plugs and the ignition coil and she's been running great ever since. I know a lot of people talk crap about the boxer engines, but I didn't think it was that bad of a fix.

[@lauriergauthier5368]

@@RIPdBOON I wish i could say that about mine I have spark on one cylinder and it won't start. what baffles me is i only have spark to one cylinder when it is a wasted spark system

[@pansaint2662]

I have a 2012 Subaru Forester 4 cylinder I did 4 4new spark plugs and 4 new coil packs only codes I get is a permanent misfire in all 4 cylinders I checked all hoses and replaced throttle body and still misfire in all cylinder ?? Help does anyone know what the problem is?

[@cedric5323]

Check the coil pack. Each coil wires go to the coil pack. Unbolt it and check for continuity. There are youtube videos showing you how to do it

[@WickedCrispy]

10:16 Those cover plates are so stupidly obnoxious to remove and put back on.

[@bobhunter9439]

Any advice for a choking 2015 Outback 2.5l. No error codes or engine light coming on? It chokes only at around 1500 rpm's. it's not the PCV valve, that's new.

[@GSmith-je4gl]

Let me know if you got this resolved. I have the same car & same problem.

[@577buttfan]

great video bro lots of knowledge.

[@mrfester42]

If the injector test shows the correct resistance reading, is it still possible that the injector may be clogged and thus still not functioning as it should?

[@DavidS-iq4oo]

[@arnaudmalan2594]

Great video indeed, in SA they charge USD 180,00 for a new set of spark plug leads. So USD 50.00 for the ones installed in the video is a pretty good deal!

We really appreciate you bringing us these Subaru diagnosing and repair clips. Thank you.

[@cedric5323]

I'm not a mecanic but from the research I did, I would check the EGR valve "exhaust gas re-circulation"

[@lv2fishrn971]

I have issues on cylinder 4. I have replaced plugs wires and coil pack. I have 238k miles. Maybe time for a new injector? Or maybe the wire harness that pluggs into side of coil pack is damaged?

[@arieswrld5536]

i’m having the same issue right now! Did you end up figuring out the problem?

Dude, i love you!

[@pitviper7924]

I am a retired electrical engineer. Through my whole career, if I needed to fault find with electricity, the multimeter was the most used. The oscilloscope was second. For this type of trouble shooting, a cheap Harbor freight multimeter will be sufficient.

[@sicklecell9999]

THANK YOU! I'll try this next. I have gas leaking into my oil, a lot. My injectors all sound like they're click'n/working fine. No smoke out of exhaust, no 'check engine' lights, car starts & runs ok. maybe it's not getting spark on a cylinder??

[@Rustyrailhead]

Like others , well done video. I have forester that all of a sudden while driving started running rough. No check engine light. Go figure. Thought these things knew everything about the car.Any comments

[@undertaker6fd]

Probably won't see this since it's an older video but would the process be the same if you are only getting a misfire when the AC is on? My 2006 WRX runs great but within 5-10 min of running the AC I get a cylinder 4 misfire.

[@luisrojas4517]

I have Subaru Impreza WRX STI 2008 no turbo problem is star in off mechanic no find the problem

[@StanTheMan-us3tp]

Similar issue, What if the wire is arching when you remove it? Does this necessarily mean the wire is working ?

[@MrZbiggles]

great video, well spoken and perfect camera angles. would hurt to mention what size sockets they are. Subarus are great cuz theyre usually 10,12, or 14 mm.

[@theoriginalmungaman]

Can’t the injector read correctly but still be bad?

I had a cylinder one misfire. So I changed spark plugs and wires. Then after pushing some gas, all cylinders misfired. So I replaced the coil pack. When I replaced the coil it wouldnt start. But then I got another coil. Lights off again. If it doesnt stay off ill check injectors. But so far so good.

How did it go, tho?!

Just because it's new doesn't mean its good. shame you got a new faulty coil the first time.

[@dalebechtel8904]

What does it mean if I have misfire code but when I pull the wire the engine does begin to shake and stutter

It means the misfire is probably intermittent.

Perhaps carbon deposits are causing increased compression ratio.

[@Nbomber]

Probably carbon buildup. Something in that cylinder is getting too hot. Could be so many things. Valve not seating properly, and thus getting too hot, or an injector worn out and not providing enough fuel. Or carbon buildup. Id look at the injector first since its easiest. Get it out, clean it up or replace (usually requires ecu programming for calibration) and see what happens.

Does a wet plug mean the injector is working? Or can it overfuel? Had the P0301 and bad miss. But after gapping plug and checking the wire, and still throwing the same code, suddenly miss went away and not throwing the CEL. I'm guessing coil but haven't tested it.
