What Caused My Jeep Gladiator Engine Misfire??

In my last video I made a trip to pick up a 392 Hemi Swap for my 2010 Jeep JKU. On the trip, my 2020 Jeep Gladiator started stumbling, running rough, and then finally displayed a flashing check engine light. The code was P0302, which means misfire on cylinder 2. The flashing engine light means its an active full misfire.
In this video we pull the JT into the garage to figure out what went wrong!
The 3.6 engines in these and the JL have had some misfire issues in the past. Alot of people reached out saying they had issues with cylinder heads, auto start battery issues, and even issues with the ECM causing misfires.
Recently, i added a set of RIPP high performance coil packs. They did make a noticeable difference, and looked to be made very well. My first thing to look at would be these coil packs..
Hopefully this video helps out someone, its important to remember what all goes into modifying our Jeeps.
We will see how long the other coil packs last for. Hopefully this will not be a continued issue, but we will see.
Thanks for watching, and i cant wait to start up the JK Hemi swap, which also means we need to finish up the LJ LS swap.

This is why most engine mods aren’t worth it, especially when under warranty...unless you just want KZbin content.

[@REDMAN298]

Wise words. There`s a drag racer I saw interviewed and he mentioned ignition is the last thing to mess with due to little gain.

[@sergvegas5446]

He keeps messing with a perfect gladiator, IDIOT!🤣

[@aaronhahn777]

or unless you just really want a supercharger. That's probably another good reason :)

[@JeepGearGadgets]

Lol I love how you said “smell that”? With the spark plug as if we actually could😂

[@turboponies]

FYI - Ben lives in the future when he can send the smell over the internet via voice commands, but your dumb device in 21st century can't receive it. I actually smelled poorly-refined unburned mineral fuel. Duh!

[@JustinKingOffroad]

i've smelled that smell before... i smelled it when he said that hahahhaa

[@PNW_Car_Mods]

I could smell it just fine. ;)

[@jasonh4167]

??? I did dont you have smellovision?

[@JeepGearGadgets]

Hahaha smellovision. I’ll admit, I did sniff as if I could smell it when he said that. I wasn’t the only one who got tricked by it😂

[@seventeenreasonsails]

That was a dirty trick, when you held the spark plug up, and asked if we can smell it!!! I actually sniffed!!! I am glad my wife didn't see. I am glad it was a simple fix but I am going to watch for a wile before I start grabbing coil packs.

[@capt.stubing5604]

Glad to see you followed up and owned the issue.

[@AdventureAwaits4u]

Coil packs rarely make more Dyno proven power unless it is a heavily modified motor. Stay stock. 😊👍🏼 Glad you got it fixed and keep up the good work.

[@JTDTV-cu3gr]

Best Jeep video on KZbin hands down! He go’s over installing and review’s of parts like they should be not 10 min after there installed but after running them for a wile. Great work my man.

[@somewheretoday]

Keep those videos coming. We learn by experience what to mess with and what to leave stock.

[@JeepGladiatorestAprilJTR]

Thanks for the video. I’m definitely wrenching on my JT and JK. Dealers or shops are super expensive. Videos like yours, make me feel more comfortable working on my own rigs. I have a cylinder 1 misfire. Thanks again.

[@w0wsuchdoge]

You always mention you don’t wanna make the video too long but dude I don’t think any of us mind, the longer the better

[@weinowei143]

Always love how detail your videos are. Awesome. Didn't know you already pull two V8 for engine swap. Freaking awesome

[@jackwitt8713]

Great job on the diagnostics,Ben. Love the channel.

[@jackknutel1083]

Thanks for making KZbin videos, I always enjoy watching them. God bless✌🏻

[@frankwrogg2515]

Great example of a self inflicted problem that did not need to happen.

[@flashback5391]

Rip coil packs are complete junk.

[@caroleertel2961]

Glad you got it fixed! And you’re getting close to 100,000 viewers 🙌🏼

[@belajarus]

Yeah! Go Ben! Way to fixing it, great video, very humble and honest.

[@ruggedoutdoors8524]

Really like this channel. Keep up the good work!

[@danebarb1642]

Thanks for update and info on Rip pack. I have the JK kit over 6000 plus miles and now have my stock on hand with me in jeep. Hope you are up and running for a long time now. One off bad pack. Great video Ben

[@ricksscalerc2222]

What’s up Ben!!! Just wanted to say what’s up and that I’ve really been enjoying the channel and all the content and everything you got going on. Keep it up man!! 👍🏻👍🏻👍🏻👍🏻

[@717Lucero]

That kind of stuff I would’ve waited until I was out of warranty then I would do those type of upgrades. Great video👍🏻👍🏻

[@LTUSATV]

Great video as always Ben!

[@invictuscenturion916]

Good honest assessment. Like your content sir.

[@Daytona-fr7fx]

Glad the fix was an easy one, also glad to hear Ripp sent a new part(good business on their part). I like the overhead storage you've got on the single garage door side.👍

[@georgea.9684]

What good does it do to replace that faulty part with an equally faulty part though? If the problem is that the design is bad to begin with they can continue sending you new ones forever and you’ll keep having the same problem.

[@eeassa]

@6:09 tearing the entire intake off is NOT an easy fix Ben. I don't think the $300 for the coil packs plus the possible headaches they bring is worth the minimal benefits.

[@davidgroskopf7898]

I took the intake manifold off my JK before to change spark plugs it’s not terrible is it a bit labor-intensive yes it’s not terrible

[@mattbarrett41]

Meh.......taking off the intake on the 3.6 isn’t a big deal. Takes about 20 minutes. With that said, I wouldn’t have bothered with the upgraded coil packs. They deliver electricity for spark. Either there is enough electricity for spark or not. More fuel & air make HP

[@GenCab]

Do it once and it's not scary or a big deal. This has to come of for multiple repair items and dave's you a fortune with minimal effort. Give it a try.

[@jeepnutscotty]

Value for money... this is not a good upgrade imo. Unless you have significant performance mods to support them... i.e. a full built engine, not a stock one

[@garyhenion9459]

Great stuff as always Glad it ended up being a easy fix

[@johnthibodeaux5189]

Man today’s engines aren’t like they used the be. So simple to work on 70-80s engines almost anyone could soup up an engine. Now days they are like apple computers...no user modifications. So much electronics computers etc it’s almost detrimental to try and soup up a modern engine. Glad you found out the problem. Let us know if another coil pack goes out so we can avoid

[@justin________7477]

New to the Jeep and 3.6 scene. Thanks for this info, if nothing else, it's good to know what's needed to get access to the spark plugs and coils.

[@aguywithajeep]

Second Ripp coil pack failure I’ve seen this week. That’s a bummer

[@danwilson2560]

Love the Gladiator, but I'd leave it alone and focus on that badass JK. The Pentastar performs great as-is. Maintain it well and it'll serve well longer than you'll probably want to keep it. Let's see you get that V8 into the JK! I always enjoy your videos! Thank you for making them and giving us a little getaway during these rotten Covid times!

[@TaskForceOffroad]

Glad you got that figured out this now the 3rd coil pack ive heard of going bad from RIPP i personally havent had the issue im about 10-15k into my coil packs with the longest drive ive done with them was 3.5 hours towing 2klbs not sure if i got lucky or if its coming down the pipeline for me as well

[@JeepJL]

The oil weeping is coming from the Variable Valve Lift Solenoid seal. It’s a common issue. Replacing the seal doesn’t always fix it either. Sometimes a whole valve cover replacement is required.

[@MrAggrosk8er]

I searched through so many comments for this one! Haha. I appreciate you.

[@anthonygendron9737]

Boy I’m glad I saw this before I bought them.

[@pennypackmtb2542]

There's a satisfaction that comes with doing the work yourself and the knowledge on the quality of the work. With KZbin videos like yours available, how could you go wrong. I've always believed that once you "Modify it", the warranty is void, as printed in the tiny print. So if you are planning modifications, be careful not to purchase a warranty that will conflict with your plans.

[@SQLRYAN]

Good to see it was a simple fix.

[@ssrevo007]

Glad your still 392 ing the jk.

[@x7tristan]

Had the exact same issue with my ripp coil pack, same cylinder too. I just went back to oems on all 6. It's a pia to get to those!

[@gen2-x364]

If something isn't broke don't fix it. My take on aftermarket mods at least on V6 engines.

[@joewe23]

Amen brother

[@mikehoffman3690]

Great diagnosis.

[@jasondokken7920]

I've run the Ripp Coil and plug wires on my 3.8 for over 20,000 miles with no issue, just my experience with them. I've been happy with the performance of their product.

[@dylanwilliams9993]

Of course it's not easy to tear into for the coil change. New vehicles are all the same so you take it in to have the dealer to repair. Video gives you what your into doing mods. Really looked not too bad. Great job!

[@calihuntfish7163]

Thanks for the heads up, won’t bother with ripp

[@BuiltForDirt]

Yeah like you said Ben lots of people selling their JTs. Not sure why but I’ll be keeping mine that’s for sure.

[@15jwrangler]

Love the jt, can’t wait to purchase mine

[@kyledean6659]

That drill on your fender is making me nuts

[@melvinortiz04]

I thought it was my OCD kicking in. 😂😂😂🤦🏽‍♂️

[@nutronik9]

I have these installed now. I just got home from flying out, and on my drive home I got a p0305. Thankfully I was a mile away from my house. I just got done putting the old one in place of the bad pack and no more misfire. I had the updated coil pack as well. Looks like Im going back to the og packs when it gets nice enough to work on my jeep outside.

[@George71964]

Nice fix, good job.

[@ericfaley9019]

That is for the variable intake valve lift.

[@michaelhance9433]

Glad to hear it was only a coil pack and not something more in depth.

[@Tylerjschmidt]

If I’m not mistaken, that sensor is the camshaft sensor which does help advance the timing. But as far as the VVT, has a lot to do with the cam phasers which is controlled by oil pressure.

[@ricanredliner]

Everyone saying warranty is 36k but power train is 5 years 60k miles. I wouldn’t bother touching the motor before the 60k and honestly for the minimal bolt ons why even bother on a brand new motor.

[@ericmaxwell424]

I had a number 2 misfire on my JK went through the whole ordeal of changing my coilpacks and did the plugs as well since I had it all apart already. It didn't fix it and pulled the intake off again and started looking at the actual electrical connectors to the coil packs. The number 2 had a lot of oil in it. Sprayed it with some contact cleaner and it all cleared up.

[@jamesmcclain3588]

Holy shit that spark gap was huge

[@calvinm119]

Glad you got it fixed.

[@karenmorelli249]

I’m not a master tech but I’ve never known the even numbered cylinders to be on the drivers side. Always (always) had front cylinder on dri

Had a friend have a Dealership try and deny Warranty on a Trans Issue because they claimed the Oversized Tires were the cause... He got it Warrantied, but had to fight for it... Always depends on who’s behind the Counter at the Dealership 😡👍

Crocs and socks? Yup I’m subscribing!

[@bsideadventures2180]

I know yall are crazy busy. Hope yall do a meet and wheel day

[@jonathancamps9853]

I changed my spark plugs and coil packs on my 2013 jk 2 weekends ago. Saved over $400 on labor, so I spent extra on laser iridium spark plugs.

[@GenCab]

This engine has its own issues that never got fixed over the years. Cam/rocker being the bigger common problem. If you own one your should get familiar with taking that intake off to troubleshoot simple items. It's not hard and it's educational. Explore your rig and dont be scared to mod within reason. Jeep did an alright job but there is room for improvement. Remember they engineer for price, parts, stability then improvement last.

[@danhambrick6331]

Glad that solved your problem Ben.Is that a plasma cutter next to your welder?If so,how do you like it?

[@frankserafin9207]

Hi Ben, The Ripp coil packs are known to be bad. The Pentastar V6 performance group has this documented well for several months now. They also have done a dyno shootout of the various coil packs and there is no real gain either.

[@LeinadiusTheHero]

That thing that has oil around it on the valve cover, is the variable valve lift solenoid. As far as you misfire goes the first thing we do as Chrysler techs is remove the at fault cylinders coil and inspect it for burns or pin holes. Then after that we will try and replace with a know good part or swap the coil to the left bank (so that if it's the coil, then we don't have to remove the intake). Edit: the cam shaft sensor and the VVL solenoid just have oil around them. Believe it's because of the pressure from the crank causing oil to blow past

[@LeinadiusTheHero]

@Christian Emter oil catch can won't really help much aside from keeping the intake clean and potentially some other benefits. I wouldn't worry about it to much unless it got the the point where it's dripping oil down the side of the block like some poorly sealed cam shaft position sensors will.

[@vb7913]

Nice video!

[@That1Stormtrooper]

Jake, what do you put in your garage fridge? Why did you go with a side by side fridge and not just a freezer? Debating on which way I want to go. Great video btw. Good luck with the coil packs.

[@MyAMSGold]

My Gladiator has 105K miles and now is misfiring. I had the coils and plugs replaced and it did not fix it and the shop can not figure it out. I have no mods to the engine. However thanks for the video.

[@joesnyder7128]

I feel you pain I had a durango with that same motor and I changed the spark plugs in it because we had the same issue it ended up being the coil pack and the insulation around the coil pack was arcing to the head, sucks you have to pull the intake! Look for white spots around the coil pack boot.

[@tonyshirley4927]

Timing on this is amazing, my light just came on, sounds exactly like yours and has the same code.... only problem is I didn’t put new coil packs on...

[@hollywood21639]

Well you should be under warranty

[@sacredshogun6325]

Glad it was something simple. 👍

[@firstdaddy]

Ben, never listen to the hate. While I personally don't care for the JT, it doesn't stop me from enjoying your content. Keep doing what you are doing and get paid. I appreciate what you've been doing with the channel.

[@biohazardshrimp]

It’s hard to beat the stock coil packs. It’s just one of those parts that you can’t gain much with and you risk issues like these. I feel the same about CAI also. Though at least those sound cool when you hammer down on the throttle.

[@jwilson2899]

I figured that was what it was as soon as you posted the codes and mentioned the RIPP coil packs. Just not worth the slight gain for the headache it caused.

[@cbrown17982010]

I’d like to know if you didn’t go with the RIPP coil packs, is there another brand you would’ve chosen? And in regards to the RIPP’s have you noticed any noticeable performance or mpg increase?

[@turboponies]

@ 3:08 Ben, did you charge your fragramitter? My aromaceiver showed a low signal but I still smelled it in all quadro 4WD!

[@drillbittreed10]

Now I'm second guessing on buying a Gladiator if people are having problems. Great video as always.fyi I noticed the door closer on the door.is it for the kids lol

[@SCWanderer]

Obviously, mechanical skill makes a huge difference in time of repair. You have a lot of skill. How long did it take for the coil swap? You mentioned the driver's side was more difficult than the passenger side right? So a full spark plug change could be ...1/2 hour more??

[@karlpatton1249]

This was an extremely obvious problem from the start and was shocked when you said you don't think it could be your brand new Ripp coil packs. To work on cars as much as you do and that not be the immediate answer is scary!!!

[@robertgecy961]

The grime/oil in front of the number 2 coil pack is an oil leak from the front VVT solenoid seals. I have 100k miles and both of my front ones are leaking. There are also ones in the back. The only way to replace the seals is take off the valve covers. Mine will have to wait. Just did the oil cooler and plugs.

[@damoncooke8010]

I can't imagine that changing the coil changes the performance much, except for making it worse when they fall.

[@gswinlerjr]

Gotta go with a Getrag 238. You won't regret it!!

[@zmanphx]

Why did you upgrade the coil packs in the first place? Was the stock coils weak for NA motor?

[@Nickc144]

Good vid!

[@warpig1223]

I had dealt with a similar issue regarding my 17 JKU, so long story short, my Transmission went at 40k now this is a jeep that was lifted on 35s regeared to 4.56 with an air locker in the rear. sadly this jeep has lived on the pavement for basically its entire existence. I still had my 3 year 100k powertrain warranty and I had to fight 3 different dealers and Jeep themselves to get my Transmission fixed. It took well over 6 months for my jeep to get back on the road after fighting tooth and nail to get my warranty because this was not my fault.

[@jhkleinberg2]

Aftermarket coils on a stock engine is a waste of time money and reliability. Good thing you didn't bring it to the dealer they would have handed you a very nice bill. FYI you don't feel any driving difference with the coils on a stock engine. Its in your head.

[@NavyAv8tion]

I have been using the MSD performance packs on my JK and havent had any issues thus far.

[@karlschwaber7006]

I have never had an issue with anything made by MSD

[@milesmscott25]

I almost bought these Ripp coil packs for my Tacoma but a guy I know had issues with them.

[@ghaithalkiyumi8534]

all JLs have a leak in that same valve, impersonally have change it twice but it still leaking ! dealer has no answer for this

[@fraychild]

I did the same to my 16' JKU. Got the Cylinder 2 misfire code, rough idle etc. etc. Ended up putting the RIPP Supercharger Coil Packs with some NGK Iridium spark plugs and the problem went away!

[@1936fordcrazy]

Had the exact same problem with the ripp coils, ended up going back to stock coils. Had one misfiring out of the box and they fried my spark plugs in very short order

[@jthor8373]

Makes me second guess myself about getting their superchargers. Ripp wouldn't even take the failed coil packs for further testing so to improve the reliability.

[@organicmechanic8170]

@jkgearandgadgets what octane fuel have you run in the JT?

[@danarteritano1340]

Did you get other spares to have on hand if another one fails?

[@JoseOrtiz_1416]

Had same issue with these coil packs , just went OEM and no issues whatsoever, like someone else stated the amount of work for the reward isn't worth it

[@Martinez_Photos]

Great video. I am hoping that people stop liking the Gladiator so that their prices go down. Then, I will sweep in and buy one. :-)

[@TJrubicon]

My passenger side valve timing solenoid (seals) went bad like yours and have oil on the valve cover.

[@lesszabo5625]

How many people actually tried to smell the spark plug 😆 ? Curious though, did you send the bad coil pack back ,and if so, did they test it to see what the actual problem was? Great that it was not a big problem though.

[@mariosrcworld1934]

any other videos of you doing the coil/plug change? I am wanting to do my plugs and coils.

[@luismendoza2522]

Hey man..i need your opinion...I just bought my first jeep..2020 wrangler sport s...don't know much about the jeep capabilities but I'm thinking about 3.5 rough country lift with 35s .. Since I'm new to this and on a budget .. I'm not looking to do anything extreme ..will you recommend this?

[@srlewis29]

In my opinion, I think it’s best to do performance upgrades after the warranty runs out, or at least don’t change anything that isn’t a quick change back to stock.

[@mickey-eq5vw]

💯good advice especially for someone who's not a good mechanic like myself

[@RobertKohut]

Nice!!

[@moggiethejeep1828]

A friend just had RIPP coil packs fail after nine months. I’d use MSD products. They’ve been in the game way longer.

[@jimmallery294]

Yup, you are your own warranty station when some performance mods are added while under the factory warranty.

[@otm646]

There's no reason to upgrade from the factory coils until you are making at least double the original horsepower. The OE ignition parts are seriously powerful and extremely reliable.

[@martinmedina370]

How did you get the metal plate that slightly covers the coils bolt to give you enough room?
