2011 Nissan Altima, Misfire Issues 

This is the first "Altima Repair" channel to which I have subscribed. Not only is your understanding of bleeding-edge automotive electronics very thorough, but you also understand the value of "old school" hacks, like using that neon continuity tester just to check for leaks on the boot! Well done. Thank you.

I’m a master tech , I quite enjoyed your diagnosis process. Thank you for giving techs a good name. Salud , my friend!!!!

That was an awesome and informative video. I have the same exact year, engine and problem. No one - including the dealer has been able to figure it since no engine light comes on. The car runs like crap! and has gotten worse the more the dealership messed with it. after watching this, I am going to get the test light and check out the coils myself. Thank you. I hope this solves my issue as well.

Thanks Shia Labeouf, really good information video regarding ignition system and trouble shouting.

Just had a tow guy tell me today that this was what was going on with my Altima. So glad I googled it because this was a great video thanks for posting 👍🏼

You are very knowledgeable. My 2012 Altima is misfiring. I just wish I had a technician like you around to check it out. I am in the electrical field myself and follow very well your explanation but doing the repair requires equipment and experience that I don´t have. Thanks for the lesson, at least I can have a technical conversation with whoever is going to do the job. 10/30/2021

You remind me of a young ScannerDanner. I see a bright future!!!

Excellent test. All analysis is to my understanding. Thumbs up.

This dude is a certified genius if you didn't notice.

Excellent video!!! Good to see repair being done without all the expensive tools and gadgets. Just good thought process and basic tools.

Excellent tutorial information and I’m learning something new from your ideas Thanks and keep up good work

Good to see a honest mechanic

Very interesting diagnosis and use of the test light to expose the fault with the boot! Thanks!

Excellent video, thanks for the info. Electrical issues are some of the most misdiagnosed there are, damn near impossible to find a mechanic who is also good at electrical troubleshooting...so I tend to do it myself. But you.. I would trust.

Damb I wish mechanics were as thorough as u bro,keep it up 💪🏽💪🏽💪🏽

love that simple leak testing on the coil boot! Thanks for sharing! I thought injector at first for sure.

AWesome video. Would have loved to see you changing the coil wire connectors though. That would have been a great portion of the video.

First video of yours I have watched. I bought an 05 Altima that has what I what I believe is an ignition issue, which was how I found your video. Very informative and you obviously are very great and what you do and are very knowledgeable. I am looking forward to subscribing and watching your past and future videos. Thank you !

i can buy a set of 4 for under 30 bucks. replacing them all is a no-brainer. subbed.

Finally!! Your videos are always worth the wait! Thanks for sharing your talent with us. It is much appreciated.

You mad this way more difficult than you needed

This was really good ! Im having misfire issues.. Service light is blinking..On 2012 Altima 130k.. Mabye its the plugs mabye its not..my dad is on the way here.. With the proper tools to change them out.. Hopefully thats the only issue .An easy fix..Fingers crossed..

My 2012 Altima has 241,000 miles on it. It's been an amazing car! I have never replaced the plugs, but may as well since I know the issue right is a coil (or 2?). It's weird that it happened after I hit a pothole, so maybe a coil just came loose (I have not looked yet).

Didn't finish the video yet and I already put my like..Lol Was wondering where you been,glad to see you back.

Thanks for not cussing, even when you were shocked. :) Good video.

After all videos this video help, me i got the code number 6 I pull plug out an same as this guy's plug a hole in rubber I had extra one put it in an dam it's perfect now thanks for all help I just changed motor An timing chain all install an today first start thanks a lot I thought I did chain wrong 2006 nissan altima 3.5

Nice diagnosis & repair Joe and glad to see your back!!

Bro I want to thank you so much I watch your video and save a lot of money and fix my car I want to thank you very much I really learned a lot and thanks to you I was able to fix my car on my own very easy I don’t have no mechanical skills but thanks to your video save me 700 almost $1000

Very nice diagnostics Joe and good to see you back! Try not working so hard as you look pretty tired :)

Nice video, i just subscribed. I'm having a misfire issue with my 2012 Altima right now. I replaced the spark plugs, the Mass Air Flow sensor and its still misfiring. I guess I'll replace the coils next.

Awesome find! Learned something new! Thank you! Glad to see you back!

Great video man, thanks a lot for sharing your troubleshooting! Learned a lot

If you remove the bolts from the coils you can start the engine then lift each coil to see if the engine speed changes. You can also watch the coil pack spark from the end to the side of the spark plug tool. That is fast and easy. You can swap the coils to see if it's the coil or the signal going to it. There are three wires. One is 12v, one is ground and one is the signal from the computer that powers the power transistor to fire the coil. I think the center wire is the signal from the computer.

Kudos to your video, THANK YOU!

Another good vid after a long while, keep it coming Joe.

He sure does come across as being extremely intelligent.....

Thank you so much been trying to nail that down

Great to see you back Joe!

Thank you shai lebouff.

Why would'nt you just swap the coils to see if the misfire follows the coil? I really liked the trouble shooting. Nice video!!

Great video. Finding the leaks with the test light was sweet! I'm curious, though, you were wondering what the primary waveform should look like. Why did you not take a primary waveform of one of the other known good coils?

Nice video!! I learn a few things.

Interesting and informative. Thanks for sharing.

Wow. Awesome thorough job !

yes enjoyed your video, btw good to see you back.

The inline spark tester you used is great. Good job on using the inductive pickup against the tester instead of directly on the coil boot. Do you think the spark ark from the leaking boot could damage the scope?

Thanks for the info, I was able to fix my car 👍

You are the best always i wish you were here in erbil so i could open a business for you. You doing your job just like the way i want every body do there job right

Thank you for your work and dedication. I truly hope you're doing well health wise. Friendly greetings.

The shock feels good...😂😂😂 ..and it's good for you...

Yeah that hei impulse would hurt a little. I deliberately taken a little off a points ignition but, avoided the high energy. You can see it clearly on older distributor ignition coming from the spark plug wire to what ever it's arching to.

Really enjoyed that. Thanks for sharing.

Great info... Thanks, I learned a lot..👍👍

is it possible to fry the ECU when you disconnect and connect ignition coils? I have a Nissan like this and what I do is: Unscrew the ignition coil and lift the ignition coil up until the spark finds plug well or something to arc.

this guy is good

You look like the edge from u2 with the hat on. Great video as usual

I have the same symptoms and code. This video helps a lot. Thanks man

Best video ever

Trying to see if my mechanic is open tomorrow. Bought all 4 ignition coils. Was going to try and do it myself but seen the boot connection to my coils are damaged like in this vehicle. I hope this is my problem, my car sounds like in the beginning of video the way it is putts and shakes with engine light on.

Nice job. Next time you do ignition secondary with the extension lead try the clamp on style ignition adapter, might give you a better picture of the secondary and you won't have to fight with the position of the pickup. Just be aware though that due to the extension lead it will make the level of the spark kv increase. How are you liking the Vantage Ultra? Worth the dough or not?

good video welcome back

Good one man! Welcome back!

He is Hott and he knows his stuff I’ll let you fix my car anytime guy

First time watching. WOW!!! Great video!! Very professional!!! Love your approach to troubleshooting!! Keep it up!!!

Great video, while watching i was telling you to do the test light "test" 😁

Thanks for the help fr! 💯💯

Geez wonder what taht messy bare wiring and coils are all about. My wife's 2010 Nissan Rogue has original coils at 195k miles...same 2.5L engine.

Long time hopefully every thing is good.

Awesome video bro! Keep it going👍

This just happened to my 2008, same coil in the same exact spot near bottom of boot. Replaced and fixed the misfire. But, I get what feels like another misfire while driving under load below 2000rpm. Over 2k and it smooths out. Any advice? I was possibly thinking clogged injectors?

Thanks for the video, man i would really like a vantage pro about now.

Yes I have a 2007 Altima 2.5 and when I press gas in park the car seems like it wants to cut off and loses power. While driving as long as I’m on flat road the car drives but loses all power while going up hills. Any thought? Thanks

Can you pull the grey plug off the coil instead of pulling coil to see if there is an engine change or do you have to pull entire coil and boot out while it still being hooked to grey connector to check it?

You're brave brother. After the first shock, I would have stopped touching that coil. Anyway, where could I get one of those orange adaptors?

Changing the coil fixed it? Also did you change the plugs? I have this EXACT problem.

I just changed the plugs and haven't been getting any misfire codes since

So you replace the coils. Spark plugs and all the wire arnes or just the exits

How would you do this diagnostic for a car (ex. NIssan Versa/Sentra) that has the air intake above the coils? My Cube/Versa recently had a misfire after I have replaced the plugs with some ebay NGK. Believe they were fakes so replaced them with some expensive NGK ($16/pop) from Amazon (seller were NGK), hopefully real this time. Ran well for a week, then misfire came back on the same cyl(#1). Don't think it was a coil issue as it was swapped with another location. I took out the plugs and inspected them. The cyl 1 well has no oil, but the #1 plug tip was full of oil. Because all the cyl well didn't have oil, I don't think it is the valve cover gasket. My car has been down for several weeks, please advise.

Great diagnostic,I would like to buy those tools, would you mind sharing the link

Good explaining 👍

Great job Joe

My 07 altima keeps on burning the coil boot, what could be the issue? Could it be the alrernator or bad ground?

👍👍👍👍👍 thanks so much for this video

What does the white odometer icon mean??? I have that icon lit up on my car.

I know this is an old video but what under hood light is that you are using

mines throwing P0301 code misfire cylinder 1. But not losing coolant ..I changed spark plugs and the coil for that cylinder but code came back weeks later.

There he is.......we've been waiting lol.

Good job/video👏🏼👏🏼👏🏼

was getting worried buddy hope you are ok

having the same problem, how much would a job like this go for?

I could tell how many KV,s it was by how loud I screamed ! HAHA

Not trying to be a smart-ass but what's the difference between a dead misfire and regular misfire.

Something similar going on with my car anyway to talk ?

What did you do about the fraid wires at the connectors

great video thanks

Bout time 😁😉

That's a term that my husband tells me all the time, "The thingamajig" is bad so we need to replace it.

Nice job

Dude good job!

Fuckk yeahh ur the man thank u but i don't have those tools to check (snap on) jajaja the alligator check works for me
