Thank you so much for this video, did it this past sunday and car feels so much better. One swollen finger from doing the rears but better than spending $!
Nice excellent explanation on how to change spark plugs on these V6 engines. Thanks
great presentation, explained very efficiently and easy to understand
Thank you!
Great video! On my 06 Accord there is a clip attached to the bottom of the plastic cover that needs to be unclipped before it can be set aside. It holds the O2 sensor wiring.
Thanks!
And yes mine was mist likely missing from someone in the past never reinstalling it
I had the same car 03 ex white with 264000 mile just replaced tensiner pulley, next will be spark plugs.Thanks for Step by step on how to do it.
Awesome! Glad the video was helpful!
Awesome! Worked like a charm.
Appreciate the very detailed video. It’s obvious you know what you are doing, unlike all of the other videos I have seen on the topic for this car. Keep doing what you’re doing and you will help many people!
Thank you!
@@AutoFixYThere's one video that shows a few different ways how to tell the real NGK plugs from the Chinese knockoffs. Also, the NGK website should be listed below the word Japan on the box.

@@AutoFixYTsorry to be the bearer of bad news but if you are anything like myself, you only want good quality parts in your cars.
Good video. I would add that blowing out the well before removing the plug with compressed air removes any debris that may fall in the cylinder.
I completely agree, I should have at least mentioned it.
Thanks for the video just what I needed as I do my own repairs to avoid the stealership lol 😆
Nice haha, I'm glad the video helped out!
Awesome 👍,, very explain:
Appreciate it man!
👍🏻
Funny thing: That ticking noise @13:31 brought me here. Mine gets noisier when the engine is cold. I read on CZcams that it might be the spark plugs and coil pack. After watching your video and seeing how you can still hear the ticking noise, I guess it's not the spak plugs and coil pack.
Yeah that's just the injectors firing, they're loud.
Start doing videos of your Lexus GS. I would highly appreciate sir. Thanks.
I have one for front brake calipers and I have a front ball joint video that will be the next one I upload! Thanks for watching!
Does this car have spark plug wires to replace too? Ive got the exact same car...ive got p0302, p0303, p0304, p0305, and p0300 codes...I actually followed your video and got the NGKs in this video. Im still getting the codes after changing the plugs. Im going to replace all 6 ignition coils with some NGKs i found on ebay next...if that doesnt work then is there also wires that need replacing or what else? Whats the coil connected too
Wow! No wires on this car. If new ignition coils don't fix the issue then I think you should check your injectors. And before you buy the coils it may be worth either buying a spark tester to see if you have the proper spark or bringing it to someone who can diagnose this. That's a lot of misfires!! Hope you figure out the issue!
Very helpful
Thanks!
I was going to pay someone to change them for me but wow this looks so easy. I'm definitely doing it myself. I dont have a misfire either, i just dont know when it was done last and I've driven the car for about 80k miles now. I'm ordering them tonight. I have the same Torque wrench from Harbor Freight. One question though, how long did this take you (not including filming time)? It looks like it's very something very fast that takes less than an hour to do.
That's awesome! That's what his is all about, showing people that it's not that hard to repair thing yourself :)
Without filming I can have this done in maybe 30-40 minutes. It's a very easy job. Good luck!
The back bank is a more difficult reach. If you have a back brace for back problems. I would wear it.
very odd question but would bad spark plugs cause my car to go into limp mode? dont remember the last time i did a tune up,and last time i had limp mode it was the throttle body
It's possible but also with bad plugs even if the car isn't in limp mode it will feel lik that because it's literally not burning the fuel that it is given. So yiu get severe misfires and the cat will not run right. Pull the spark plugs out and inspect them. If they look worn, definitely replace them. Look carefully at them too though. Make sure they aren't covered in oil. If they're covered in fresh oil then your valve cover gaskets/spark plug tube seals are bad. If they are worn unequally, meaning some plugs look better or worse than others, that'd a bad sign too. You want them all to be worn almost the same.
Good luck! Keep me updated on your situation!
Stupid question but im about to do this on my 04 Coupe v6, how long is the extension. I bought a 6 inch one
That should be fine, I think that's what I used too
What size spark plug socket do you need?
16mm or 5/8". You can use a regular socket to take them out (not a spark plug socket) but if you use a regular socket to put them back in make sure you drop them down gently with a magnet so the tip doesn't get damaged.
Great video. My V6 mileage is not great. It gets about 25 mpg combined city/hwy. Wondering if changing the spark plugs will improve it. Thanks
That's actually very good for that car haha don't expect more than that out of a V6. They're not made for good gas mileage. They're made for power. Typically those engines will bet between 20 and 25 MPG depending on how and where you drive.
@@AutoFixYT Ok Thanks
@@AutoFixYT i use 87 octane an on my 2007 will get 320 miles full tank or 370 miles (going 75 max) for distance driving full tank. 350 in the city seems kind of high, but i guess each city may vary on how often the stop and go is.
I get 22 maybe combined... But on a long highway trip 32-33.
That's crazy! Really good MPG for sure!
If there is oil residue on the plug what should I check
Then you have a spark plug tube seal leak which in turn means you need to do valve cover gaskets. They all come as a set. So you do both valve cover gaskets as well as all 6 spark plug tube seals.
What all tools will I need? I have the basic ratchet set but I will need an extension I assume also a magnet I think?
All tools that I used are in the description. Also you can see exactly what I used in the video.
@@AutoFixYT thanks man video really helped me I had to replace a coil also lol💯
Awesome, I'm glad it helped! And also, I strongly recommend replacing all coils if you have to replace one. Of course it will work if you just replace one, but the other ones are just as old and just as worn.
Got a pretty bad misfire with 390k miles, hopefully this works!
Haha that's awesome that you got it up to so many miles! Hopefully that fixes your issue!
I have the same spark plugs, do I need to gap them? Sorry if I missed it in the video
No need to gap them. Never gap iridium plugs. They should come pre-gapped.
@@AutoFixYT thanks bro
How do you remove a stuck rubber gasket inside the sparkplug area?
Needle nose pliers or a pick and a lot of patience lol
@@AutoFixYT God help me.
Did that on my TL 😭
Yea. What’s size of spark plug wrench?
5/8" or 16mm
ACTUALLY IT'S NKG 6994 FOR THE 3.0 V-6.
5:26 Did you mean 156 inch-pounds, not 165? Thanks for the video. Helped a lot.
Oopsies, yes I did. 156 in-lbs.
Sir I have a question my customer honda accord he clean his trottle body to the other mechanic and after a week his accord drops 600rpm and it's turning off
Could have damaged the IAC valve or the throttle position sensor. Check those with a scan tool and make sure they're functioning properly. There are sensors inside the throttle body that are very delicate so if those are bad, needs a new throttle body.
One thing I noticed sir the hose connected from air filter housing to trottle body is damage I think that is the cause of low idling.
I don't have scan tools so I can't tell if the trottle body is damge
@@anthonycarlramos3358 It could be but that could actually cause a high idle... but that is a good place to start, that will need to be replaced no matter what.
Thanks for the info sir
👍
Is this car on the first transmission? I have an 04 v6 with about 185k i just did a drain and fill for the trans fluid, Car runs great but will need a power steering pump and o2 sensor soon. Do you recommend any other preventative maintenance items?
Yup original transmission! I did have to add a quart of Lucas to it because it was starting to show its age but it's still shifting great after that quart! Gonna do a drain and fill on it soon.
I'm gonna make a power steering pump reseal video in the future on this car, if you're interested. As for the O2, I wouldn't wait if you can especially if it's an upstream one. That affects how the engine runs.
Other preventative maintenance... regular oil changes. Honda recommends 7.5k miles, I suggest 4-5k especially with high miles. Make sure you keep the body clean so it doesn't rust. Change the spark plugs and timing belt/water pump every 105k as the manual recommends, and make sure that if it has any leaks you take care of them. Oil pump gaskets and VVT solenoids tend to leak on these as well as the valve covers. They're solid cars, but wearables are unavoidable. Check all your suspension parts and make sure they're good: ball joints, control arm bushings, struts, tie rods... and if you don't have ABS/Traction Control problems then good for you lol. But overall they're really good and reliable cars.
I have a 07 Accord w/198,000mi. It’s not shifting great though. There is a lag in engaging into drive and into reverse. Sometimes there is even a clunck putting it into reverse. I have drained and filled the trans fluid twice (both times came out black) Have enough to do it once more, but want to know if there is anything else I can do while it’s drained, before I fill a third time. Appreciate any feedback.
@@J88mes Idk if this helps but I have the same car with the v6 and have the exact issues that you’re describing. I did my drain and fill and it smoothed things out for a few hundred miles. I took it to a mechanic and he said that because of my high mileage (190k) on the original tranny it’s probably just gearbox chatter due to age and told me as long as it’s shifting ok, just take it easy on it.
@James Chavez: try adding a quart of Lucas Trans additive and see if it helps. 200k isn't very high mileage for those cars, and with proper maintenance they should last. Having said that, black fluid is most of the time also burnt, which is not a good sign at all. That means your clutch packs have worn out severely. In that case you're better off leaving the old fluid in, but new fluid can't fix mechanical damage so if you feel like trying new fluid, go for it.
@SuzuMR2 75: Same as I was saying above. And just like your mechanic said, drive it until it does the way it is. Add some Lucas, it might help. If you replace the fluid make sure you use Honda Genuine.
@@AutoFixYT thank you for the advice. Will try the Lucas
THANK YOU BOSS
I went in thinking was gonna be easy but i had huge trouble with the back ones and turned into a long job
Yeah, it happens! Did you get it done?
@@AutoFixYT heyooo I didn't see you responded, I did get it done my car is running pretty smooth currently. I hope I dont jinx myself!
So an 04 accord v6 3.0 has ignition coils?
Yes. One on each spark plug, 6 in total.
@@AutoFixYT thanks , so it’s best just to change all 6 coils with new spark plugs right???
@@JoinTheTakeOver Here's my take on this... If your coils are good (all of them), keep them. If you suspect one of them to be bad or of you think some are worn, you want to replace all of them. Now of course, if you have 200k-300k ok the original coils and they're still good, in that case you might wanna look into replacing them just because they're old.
When/if you buy new ones, stay away from cheap aftermarket ones, they only cause more problems and you're better with old original coils. Buy Denso, NGK, or even go with factory ones.
You do what you think is best for you but this is my opinion. Hope this helps!
Will this sp work on 2006 v6?
Yes it will! Process will be the same.
@@AutoFixYT THANK YOU SIR. HAVE A BLESSED DAY AHEAD
I have a 2009 Honda Accord V6. My check engine light just came on and it turned out one of my spark plugs was fouled. The light was flashing and the car ran really rough at low speeds. I limped home and had it towed to the shop. The shop said there is an oil leak causing this.
They also said that the other plugs looked OK. Am I to assume that there is possibly some sort of issue with the valve cover gaskets/spark plug tube seals? the reason this is worrying me is this has happened 3-4 times over the last couple of years - 15-18k miles. I don't drive rough and the car runs beautifully right up until this happens with no warning.
Have you heard of some people (mechanics) believing the VCM causes this? They believe the engine stopping some of the cylinders could allow oil to seep through.
My car only has 155K on it and I was hoping to take it to 200K.
That's a very odd issue... but yes the VCM can definitely cause issues. This type of system has been known to cause issues for multiple manufacturers, not just Honda.
Having this same issue with my 07, it's been well maintained an only 95k miles...I'm replacing all spark plugs today and doing oil change. Confident problem solver I believe lol
@@smokeygreene9110 let me know how it goes please
Can you please let me know if permatex can work in place of dielectric grease? Permatex 22058 Dielectric Tune-Up Grease, www.amazon.com/dp/B000AL8VD2/ref=cm_sw_em_r_mt_dp_MEiXFb6BJ34SF Also I have a rubber sleeve 5/8” spark plug socket with 3/8” universal adapter with a 10” extension. I am a bit worried if the rubber will get stuck on the back spark plugs and if it falls down inside the engine bay. What is your take please?
The grease you picked is still dielectric grease so yes, it will work. And no the rubber will not get stuck, don't worry about it.
@@AutoFixYT Thank you!
I see you have the same problem as me with the hood struts, hahahaha i also use a piece of wood to hold it in place. i replaced all plugs and coils on my car, i had a mis fire on cylinder 1, now all my cylinders have a misfire...i'm gonna do a valve gap adjstment, but i'm going to check all plugs and coils first to make sure they are on tight.
Somethings definitely not right there. Check all the wiring as well as all the plugs and coils like you said. Make sure you have the correct plugs. Something like that is no likely caused by a mechanical part such as the valve adjustments. If that was the case it would have done it before. Make sure you didn't accidentally unplug any electrical connects that need to be plugged in and also make sure no vacuum hoses came unattached. The best way to go about this is to have a scan tool that can tell you what each ignition coil is doing, or at least something that can count the misfires on each cylinder. But if you don't have that then start with the basics and double check all your work. Again, something mechanical would have been present before the new plugs as well, it wouldn't have immediately appeared after the install.
@@AutoFixYT gret! thanx for the tip!!
@@AutoFixYT so i solved the poroblem..some moron put diaelectric grease..that clear one you get when you buy plugs, he put that grease inside the coil for some dumb stupid reason...so the spark wasnr there much...i took the plugs and coils out..cleaned them out..put them back in..and the problem is solved.... TIP...don't out that grease stuff inside the coil boot..put it on the ourside.
Awesome! I'm glad you solved the issue! As for the grease, you can put it inside as long as it's the appropriate kind of silicone paste / dielectric grease. You can't put just anything you want in there. I like to use 3M silicone paste because it works on all electrical connections and is great for rubber.
But I'm glad your problem is solved!
Great job. Going to try it next weekend. Thank you
Are those Allen or Torx bolts?
Which bolts?
@@AutoFixYT sorry...the Hold down ones for the coil paks.
@@dgriffin6074 Those are allen heads
Is the silicone paste mandatory?
No, but it helps with corrosion over time. I've installed many without silicone paste.
Did you purchase your plugs from Amazon or your local part shop ?
Amazon, link in the description :)
Thanks for the reply I was worried because someone told me Amazon plugs come broken and never work considering yours did I’m more confident with mine’s coming in today 👍
@@antoniomorales1605 I always buy spark plugs on Amazon, and they never come broken. I think it just depends on what brand you buy. NGK brand has a protective sleeve around the tip so it doesn't get damaged during shipping.
Local shop was going to charge me $200 not including parts.
Thanks
Saved yourself some money, awesome!
I have a 03 accord v6 and my hood struts don't work either lol
@chrisclayton2068 Haha classic, they all go bad.
I always have to gap the plugs for my accord or it will misfire for some reason
You might be buying the wrong plugs then. They should be pre-gapped and you're not supposed to gap platinum or iridium plugs. It damages the coating on the electrodes.
Such a compact spot for the last 3 smfh
Not that bad, I've done way worse lol
It's good practice to use anti seize regardless of what's on the threads.
Not true. Using anti seize on modern day spark plugs will cause them to be over tightened, and can also cause them to back out of the hole by themselves. The threads are coated with an anti corrosive layer from the factory. No need for any lubricant or anti seize.
@@AutoFixYT thanks for posting this tip and for the very clear information. I bought all the supplies and tools and gonna give this a try... Wish me luck 😂
You can do it! It's easier than you think. Good luck!
@@AutoFixYT so I replaced the spark plugs.... It all went smoothly until I got to the 4th one and there was oil all over the ignition coil... The problem is bigger, I think, so Carla (my '03 accord) is officially cut off at 387k miles and will now rest in peace 😊✌️😎💐
@@lauralime usually that just means you need new spark plug tube seals/valve cover gasket. I have a video on that. Super easy and cheap fix. If thats all it is, I'd say keep her going! That's a lot of miles, I love high mileage vehicles!
The only thing missing from this video was giving the audience a map of cylinder numbers.
Good idea! I will add that next time I make a spark plug video.
I immediately laughed because my hood doesn't stay open too. 2007
Lol yeah they all do this eventually
Looks like you need to replace the hydraulic hood pistons
lol
Yes lol
The rear sparks are is the hardest to do
Not that bad though. Doing them when you have an intake in way and you can't even reach is hard haha
