- So in today’s episode we diagnose a cylinder misfire in my little brother’s 2015 Jeep Wrangler with apx 80k miles… This is by no means a how to video… This is purely for entertainment!

Still love this video after all these years ! The shaking of the camera 😂😂😂😂 sorry y’all go fast don’t die DV
Next time take that hood and push it all the way against the windshield frame. make life easier.
You inspired me to try this on my own. I’ve got the same problem. Thanks for your service guys!
Update: worked like a charm! Only had to take the plenum off one extra time because I forgot the insulation underneath it the first time.
Did it work? You
@@DeterminedVeteran It did! I actually had to do it again for a different cylinder a few months later. While I had the plenum off, I also changed the plugs and coil packs. Thanks again for the video and especially your service.
Thing is, it takes a while for check engine light to light. Did it stay out? I’ve changed my coil pack and plug and still issue
Could be your rocker and lifter broken
It's always good to look after little brother.
Most definitely!
Hi I have a 2007 Liberty 3.7L V6, 117,000 miles. Owned it since 67,000 miles. It operated perfectly for the first 30,000 miles and then it started getting a #1 Cyl misfire code P0301. It also seldomly gets a #1 cyl fuel injector circuit open P0201. It must be a very mild fault as the misfire freeze frame data shows it always happens at less than 350 rpm and when cleared it comes back immediately at next startup, cold or hot. So it seems to only happen once on startup as its moving up to regular idle speed. The miss isnt noticeable when driving or idling. Its getting 15.5 mpg fuel mileage. Doesnt burn oil. Doesnt smoke. Has great power. I've changed plugs and coils but no difference. Cleaned air intake, air filter, and ran cleaner through system. I've cleaned and inspected the injector plug and all wires but no difference. Dry / wet compression test of #1, 3 and 5 cylinders all read good: 160 / 175 psi.
I'm wondering if there's a mild wire defect for that injector, or just a flakey connection somewhere. Has anyone tried to use a new set of compatible gauge wires and run them to a place closer to the injector control? I can't see where the wires go though.
I'm not sure if I should just live with this, or troubleshoot it more. I don’t care about the engine light as we don't have emission requirements. Now that I know the compression is good, I'm not so worried about it.
Any suggestions of what to do next? Thanks!
Did you ever find a solution? Having the same problem.
@jeffryhickman9937 ohm the fuel injectors should be 12 to 15 ohms at most. They seem to fail and start missing about 30 ohms or higher.
It’s ridiculous how much you have to remove just to change out the spark plugs and/or coil packs.
2014 jeep wrangler sets code p0303 after reset sets code p0741
These 2 codes is se after you drive
I never shut the hood on start up after repairs.
Fuel leaks and fires can be nasty….been there.
The Wrangler Sport is so capable and a ton of fun to drive! What lift kit is in it / how much lift? It's always great to see brothers playing together with their toys!!!
I think he is running a 3.5’ lift from Rough Country .... but he has done so much since we made that upload
I know is a pain in d but to remove that air intake ….great job 👍
Just wanted to say Semper Fi to the jar head
I saw his Tat. I was in 1969-1972. Nam veteran. I would do it again. Maybe the rations are better now. Thanks for the tips.
Dedicated follower but this one popped up by algorithm on my home page , keep killing it bro , I think ima try make a blog of my roadking installs, Thrashin supply bars
Lol this is an old one for sure ! Ton of fun making this upload
use rubber knee pads that the masons and carpenters use when climbing on top of engine. the blue pair
Nothing like free labor! Good one man! #jeeplife baby
🤘🏻🤘🏻🤘🏻 appreciate that it was a ton of fun to make this one
Glad this worked. Thank you for the demo.
haha..."It's a straightener fro my beard"...lol. This was entertaining. Happy 4th of July in January 2022.
Man this is an old video for sure lol
6 hours? I have same jeep. I did plugs in 2 hours. Stupid intake has to come out.
We filmed bs and took our time lol … glad it worked out for you as fast as it did
Funny thing. I got the p0302 code so I went and purchase a set of spark plugs, disconnected the battery and realize I had the wrong socket to remove the spark plug. So I returned the cable to the spark plug and reconnected the battery. Now there's no engine check light, no codes and my OBD2 shows no codes also.
Any reason why??
When you disconnect the battery longer than 10 seconds it resets all codes
Good job guys! This was entertaining to watch!
🔥🔥🔥💪🏻💪🏻
I did a Magnussen supercharger on my 13 JK MW3 edition. At 40,000 I started having #6 misfire codes on thr Diablo code reader that I got with my SC kit. It's a random "check engine" and it runs fine normally even when the idiot light is on. It does struggle at times like bad gas. Knowing the '13 had head issued, I've always been worried that it's not a faulty coil pac (why work intermittently and not just fail %100?). I've got 60k on it now and it's to the point where I won't drive it anywhere like out of state for fear I'm doing more damage.
The jeep dealer won't deal with it since my aftermarket supercharger, so I'm stuck DIY.
It's such a hassle and winter in PA now, so thus will be my first spring time repair. New plugs and new could packs. A trick to diagnose is to swap coil paks 6 and 4 (or whatever is easiest access) and see if the misfire follows the coil pak. (In this case, the p code would be xx04 vs xx06?).
I'm hoping it's just the coil part and I don't need to swap out the whole head chunk. In '13 (early to mid yr builds) the exhaust port was milled to closely to the cyl wall, and eventually fails/communicates with the cyl. It was a long requested recall, but my supercharger nixed that option.
Thanks for taking the time to check out this OG video here on the channel flash forward three years later I moved to Allentown Pa and still making content !

Appreciate that!

Thanks for the UA-cam advice determined vetran
🤘🏻
so did it fix the problem? I have swapped out the coil packs and after replacing the battery, the first start no code or engine light, however, after the second startup the engine light comes on and the code pops back up on #1 and #2.
Yes it did.... we replaced all the plugs and coil pack 6 .... filmed this several months ago so my memory is a little foggy
My jeep misfires after it’s warm and I shut it off then restarted, apparently it’s the fuel injector. FYI for anyone with the same problem after a complete tuneup.
The number 8 cyclinder on my truck took like 2 hours it was 2 hours and 7 minutes for the spart plugs
Is it also a mopar product as well?
I have a 2008 rubicon with 3.8 with random misfire p0300 i have changed the spark plugs wires and coil but the problem is still happening any ideas?
Check for vacuum leaks
@@DeterminedVeteran yes im thinking it could be the map censer o ring ill go over all lines also thank you
Did you ever find out what was misfiring I done replace everything you said and still haven’t fixed my misfiring on my jeep
Hey I have a 2015 jeep wrangler... Same code but I'm getting different answers on cylinder 6.. does it change on mine? . I'm told my 6 is on the driver's side?
Ur brothers is a 2015 as well.. Ima go ahead and change 6 on passenger side.. did the code ever come back?
No sir it didn’t ! I asked him a few weeks ago ... good luck
Next time just take off the passenger fender and you will have an easy job replacing the spark plugs! took me 1 hour to replace all 6 plugs.
Thanks for your service i salute you👍
Thx you !
Best job I ever had !
Awesome video! New to the channel but you mentioned Fort Knox so I assume you’re from Kentucky! Not far from ya! I recruit for the Guard out of Campbellsville!
Actually from Texas retired at JBSA and currently live in Pa where I make my content now
This is one of my first big hits
Enjoy driving dear.have a nice day
🤘🏻🤘🏻appreciate that
Have the same error code, mechanic changed the coil packs and same code. Now wants to rebuild the engine
Oh no
I have a 2012, changed out spark plugs, coil packs and injectors and I still have a misfire in #5. 🤬🤬
Have you found the problem yet ?
Check the lifters and rockers
Love the flag on the wall!!
I have a 2011 wrangler jku. Sounds like exhaust is misfiring.. Sometimes it takes 5+ key turns before it decides to fire up.. No check engine light.. You think it might be sparkplug problem?
It’s either that or the coil pack ...
@@DeterminedVeteran yea i was thinking about replacing the fuel pump, it acts up sometimes and it turns ober but doesnt fire up, it takes about 5+ turns the it finally starts but real sluggish, but the backfire you can feel it inside the jeep while idling
Is a 2011 with 93k miles, is just weirs that is not throwing any check engine light codes.
A fuel pump won’t necessarily throw a code especially on mopar products my Nieghbor has a Ram it was acting up and I replaced the fuel pump and it’s been running strong ever since
I had same code but plugs,coil pack and injector did NOT fix it. Any other ideas other than replacing the head?
Not enough info to give you an answer ... what other codes symptoms are you having ?
@@DeterminedVeteranI replace the Ecm, coil pack, spark plug and install a new engine still has misfires! Please help me out buddy
@@jordygonzalez1317 check the lifters and rockers
love the color.
It’s patriotic blue
Merica!
@@tbornman89 mine is gray.
Its the beard guy!!! Where’s his beard straightener?? 😜🥰💁🏼♂️
Great question 🤔
Any chance he was getting a p0306 code mine is saying I have a cylinder 6 misfire and I’ve already changed out the spark plugs and coil packs and every time I clear the code it comes back just wondering if this is what I need to do to mine
Yuup same code my man ... sounds like you got a challenge on your hands good luck
Lol I bet it came back on right after the video I ended up replacing the plugs coil packs and injectors and relized it was gas cap lol but it runs great
Lol no sir ! Been running like a champ
@@DeterminedVeteran glad to hear bro thanks for serving
You were getting a misfire code and the gas cap replacement fixed it ?
Awesome Video! I am getting the same error code!
Thx so much yeah hopefully you were able to get it worked out ... I’ve heard from others even after they did what we recommended in the upload they’re still having issues
@@DeterminedVeteran Sounds good! I am going to swap out the spark plugs/Map Sensor/O2 sensor this weekend. I'll shoot you an update to see if that did it! Thanks again!
Watch the old video. Got to fix my oldest son's car tonight. Vvt silonid's. And such. More of a old school mechanic.
Thanks brother ! My god this video was very early on in my UA-cam career ! Thanks so much for checking out our content and being a member of our community
Hey I feel your pain, been there.
Shockingly it went well...
😂😂😂😂 The Beep lives
Misfire on cylinder 6... that's exactly what my problem is. However... my Jeep is only 3 weeks old with 900 miles... WTF....
Did you find your problem?
@@wadedog4280 Dealer spent 2 months trying to fix it. Turned out 2 cylinders were having a misfire problem. I purchased the Jeep from Arizona and drove it back straight to California right away. Not sure if it was because I tested the car right away with the long journey or what. It has been running great after since.
😂 I cant
Good job guys!
Thx ! It was a blast doing this video w my little brother
Another good one!!
