Thanks for the video. I would recommend putting a large rag over the intake once the plenum is removed. You do not want to drop a bolt or anything else in the intake.
I just want to say THANK YOU for your videos. 2 days ago the 05 quest started shaking and stuttering and the CEL flashed on. I keep a scanning tool in the van because the P0420 likes to come on at times and I just reset it. So the code came as the same cylinder #3 misfire. Ordered the parts on Sunday, locally, and called as a "what the heck" to my two mechanics to see the cost of labor. $300. ugh. So spend several hours on Monday looking at the videos to see how to do it myself. Very slow and methodical, and struggled with that one bolt on the back bottom right of the intake. If it wasn't for that, would have gone quicker. also, a socket fell as I was trying to finish and putting the two bolt on the back of the intake ( the two in the back bottom closest to the firewall, not the group of 4 to the intake). Luckily, the last time my mechanic redid the valve cover in the back, the green connectors were left unattached from that bracket. All in all, took 7 hours for me, which included lunch, breaks, two trips to the auto parts store for that torx socket and another stubby ratchet, since mine was too fat, and alot of latex gloves!!! But I saved $300, actually more as I got 3 ignition coils on sale for less than the price of 2 at the mechanic (if I took it there). I opted to do all three at once, with new plugs, because I wasn't going to do that again. 1 spark plug was actually cracked on the tip. So glad I did them. You Rock!!!!
I found it a lot easier to remove the entire upper plenum with throttle body, and I highly recommend anybody doing a tuneup on a Nissan or infiniti to replace ALL coils at the same time to prevent having to take it all back a part again lol

Mike Thompson I agree! I hope he doesn't get rid of this vehicle for a while because I have the same one. If something goes wrong with my van this is the first place I go.
I don't think I've ever watched a video that was completely void of troll comments. Congratulations! This speaks volumes about your professional quality video. I even liked your choice of music. Exactly the right length, detail, and pace. I got a quote for $700 to have mine done on my 07 Quest. After watching this I may take a stab at it myself. My Quest has over 200K and it has a lot of other issues. Very well done and thank you!
I just wanted to say thank you for this video. I was able to replace all 6 spark plugs and coil packs. The only thing I skipped is I didn’t remove the air filter box. Took me 8 hours to do the whole job. I took my time though and labeled each bolt and placed it on a ziplock. Overall not bad. This is my second time doing it
I did my 05 Quest and I removed the two bolts holding down the back bracket it’s showing on minute 4:35 instead removing all four bolts it was a time saver and easy doing it that way. Thank you for posting this great video
Thank you for sharing your expertise !! Exactly what I need to do to my 2005 Quest. My No. 1 cylinder is coding a misfire. I haven't checked under the hood yet though. I'm hoping they put my engine in backwards so I can get to the cylinder easier. You know, like they do for European models because they drive on the other side - fingers crossed 🤞🏻
I am with you all the way when it comes to buying parts; in that most of them should be Nissan parts This goes with MOST things you buy. Yes other parts manufacturers will save you money for sure. But they often cause aggravating problems too. Believe me I have experienced this many times in my 88 yrs old. And so have many others had the problem. For what it's worth, I disagree with removing the "studs" when removing the intake plenum and EGR parts. Simply remove the nut. There is simply no need to remove the stud. Worse; when you remove the studs it is easy for the gasket to move from where it is suppose to be when installing it. Even a little bit it can cause MAJOR problems in the engine. I can not emphasis this more. For, IF that gasket moves slightly from where it is suppose to be, you can have a problem difficult to find in the future. The sole reason for the studs; are to stop this problem. Please consider this. Practically, this can be proven with common thinking. IE: Why are 3 of the intake plenum fasteners "BOLTS" and yet 2 are "STUDS"? They could have used 5 bolts and it would fasten the plenum the same. Again the studs are to insure that the gaskets are kept IN correct place. In fact the shape of the gasket is designed to stay in place; while installing the intake plenum (manifold). NO disrespect meant here. I am simply trying to keep DIY'rs from a problem when working on their cars; that happens a lot. Believe me. The same problem is with the EGR replacement. Never remove the studs. Simply remove the nuts and change it. This insures that the gasket stays on correctly when tightening. Again, no disrespect. I love your video's.
To be fair, getting leverage on those bolts in the very back behind the intake’s first part is a bitch, but yeah, it is generally easier. That’s the way I did mine
I've just done a "tune-up" of a 2008 Nissan Quest for a friend. It was misfiring on cylinder 3. When I got it apart, it was clear that the coil boot was faulty; there were electrical burns on the seam in the middle of the boot where it was arcing to the spark plug well on the head. Long story short: I succeeded in replacing all of the coils and plugs because their replacement were due anyway (though I still would have replaced them all because I don't want to do that again for a long time) and now she runs as smooth as high end scotch. But this is a job I never want to do again. Too much damn work just to change the plugs and coils because some nimrods in engineering and/or beancounters in accounting couldn't give the vehicle an intake manifold that's easy to remove for servicing the engine on the side with the odd-numbered cylinder bank. Another post here said that the owner got a quote from a shop for $700 to do the work. That's not far off the mark for the labor plus parts.
I have the same problem that u mentioned so now I think it is my coil packs because all three is black and probably the ones in the back are too and I'm going to replace all of them thanks for showing me the problem in your video I needed that truly
Great video I'm in the middle of doing my tune up going to change valve covers and coil while I'm back there I also did my front struts figured with the cowl off might as well.Thanks again for the great video's and advice.
Ray, I'm buying front struts for my 2004 Nissan Maxima 3.5. I recently watched a vid about how to uninstall and install new ones. The dude didn't show removing the cowl. Am I missing something here?
Replacing Ignition Coils : Step 1 - Remove windshield wipers. It just seems so wrong to me ! But there it is ! I never would have believed it......... Thanks.
Out of curiosity, how long did it take you to do the whold thing? I imagine just taking apart the window cowl and plenum feels like 2 hours alone. At any rate, I am happy your vids exist. Thank you very much.
Great info. It was exactly my problem. The layout was a bit different what you described but the solution was the same. The coil that was bad on my 02 Pathfinder took 20 minutes to remove and replace. Thank You.
I have a 2002 Nissan Maxima SE 56,000 miles 19 years old never had a spark plug change in it's life, started misfiring check engine light on, took it to the Nissan dealership they installed 6 new spark plugs 6 new coil packs, a rocker panel and the gasket paid $2685 more than the cars even worth but I gotta say it runs like a top lol
A misfire can also happen from loss of compression in the cylinder (bent or broken valves). It would be better to do a compression test before replacing the coils. Because you might have spent time and money and still have a misfire.
Just had my 2010 Honda Odyssey do the same thing last month. Immediately brought it back to the Honda dealership and told me that there was a class action settlement that resulted in compensation for repair and warranty extension for this particular issue. Honda changed out the required parts and changed all spark plugs. I have a link if you're interested in regards to the class action suit since you have the same honda vehicle.
Thanks for all Quest series videos You share with Us , I have a 2004 quest and was my time for this misfire P0303. For same reason which I don't know My quest was working ok when I was turnin on the A/C. sound crazy but happened to my quest , so I purchase one Ancel which shown P1800 $10 parts easy fix... I was so happy , but after 5 miles driving P0303 come back and this time A/C was not able to stop that P0303, so I started all what you did plus I ordered all those Nissan parts for the replacement and after all that work to be done and right, I Started my Quest and got P0301 and after while (2 minutes I guess) P0300 ..... Any Idea what can go wrong ? I'm trying to figure what is wrong Thanks again.
Been following you for a minute, and you always have great content. I have a p0300 code, which you explained at the end of your video was the last number represented the cylinder. P0300 I'm lost trying to trouble shoot which cylinder. Any idea? I have a 2006 maxima with 218,000 miles, and I'm thinking more towards the catalytic converter.
You probably already googled it, but P0300 indicates that two or more cylinders are experiencing misfires. You might want to take it to a mechanic to have them troubleshoot it since it's multiple cylinder having issues. If you want to tackle it yourself, you can first try replacing all 3 coil packs and spark plugs on the front side, and see if that fixes it (since the front side can be replaced easier). If that doesn't fix it, then do the back 3. Also the plugs need to be replaced every 100k miles anyways.
I just change my coil pack, put new spark plugs because it had po303 code, it needed them change, great videos, done all that work, still driving the same way, they said it could be fuel filter now, do you have a video on changing it
These engines have a problem burning up ignition coils, inspect your battery ground cable, it probably goes down to the firewall and then down to the transmission, it likes to break at this point and the large current produced by the coil has no way to go to a good ground so they burn up one or more coils. Give yours an inspection and as preventive maintenance add a redundant grounding kit similar to what the HIFI audio guys do. Do not bolt to plastic intakes or similar areas.
No need to remove anything but the upper plenum in order to change #3 and #5. I changed the pack on #3 two days age in just over an hour. #1 does require both upper and lower intakes to be removed.
Great video. Do you think that this is similar to a 2006 nissan maxima, US? i have a p0301, cylinder 1 misfire. car has a bit over 200k miles . Spark plugs are almost 3 years old, and maybe 20k miles. I also just had the firewall pre-cat replaced. Thanks!
The repair process will be the same for your car. If you are getting the P0301, then it appears to be a bad ignition coil, but I can't guarantee you that over the internet. Just make sure you buy original Nissan part for this repair.
Thank you for sharing your videos. This is really helpful! By any chance do you have a link to the service manual for the 2008 Nissan Quest? I have not been able to find one. The best I can tell is that it might be the same manual for the Mercury Villager?
I have a 2005 nissan quest. My issues is I have no power going up hills and as I press for more power the engine starts knocking so I let off gas real quick. It also.could be spark knock. I'm also having extended crank issues. It's starts but only after it cranks for about 5 seconds or so. BTW I am get backfire as well when I gun it to get more speed
Great video, just curious to know if a Check engine light came on for bad coils? My car is hesitant from 2700 RPM to 3300 RPM and a lot of people say it's the coil packs but I have no check engine light
misfire are caused by low compression foul spark plug bad ignition coil and loose injector and coil wire connector what if you change the coil for p 0303 and the cylinder compression was low or injector 3 connector is loose half way down the road the check engine light will come back on for p 0303
Do a compression test on all cylinders also you might carbon deposit on the intake or exhaust valve that can cause a compression leak when it is on the compression stroke causing pressure to leak which can cause a missfire.
Should have replace all the plugs and coils at the same time. My cousin had a similar issue with a Ford Taurus, he only replaced the plugs in the back and the coil pack, this is a single pack for all cylinders. Ran great for 2 days then died. He found out that all the plugs, coil, and the wires also, should have been replaced at the same time. It ended up creating an electrical imbalance between the cylinders. The ECU couldn't handle it and it burnt out the coil pack. He replaced it all and hasn't had a problem since. I am having a miss on cylinder 5 of my Maxima. I am replacing all plugs and coils at the same time. Just saying would hate to ruin the 3 three coils in the back and have to replace them again. And it is good insurance to make the motor as efficient as possible. Later.
My wife's car has a similar problem, but luckily it's P0304... It has a 130K miles, so others are possibly a problem, but I think I'll stick for now with just the front center one, which should be an easy one to do right now.
@@franxiscofajardo2063, that is the front center cylinder. I have ordered a Delphi Gn10242 oe coil pack from amazon. Totally affordable for a Japan made piece...
@@thinking-laaf I already fix it, it take me 10 minutes to fix it I had saved a coil from my nissan 350z I put in on and the problem was over 👍. Good luck with you car 😎
So. Ok. The problem was simpler than expected. Makes me slightly peeved about the mechanics which replaced the spark plugs at 100K though. They potentially / likely misthreaded the #4 coilpack bolt and it potentially wasn't tight enough. There was play up and down for the coilpack when I swapped #2 and #4 (didn't notice it when I took the bolt out :-( ). I had to clean up that thread with an M6 tap and voila, the bolt went in by hand almost all the way. (I was very concerned NOT to go too deep with the pointy tap..., made sure I had at least 3-5mm clearance from the bottom of the hole - I checked with a gauge, and taped the tap off so it wouldn't go too deep... - used air to blow out the parts and oil to make sure that wouldn't cause problems, and checked the holes with a light. This 2007 Murano (In your video it's different) has a 1" wireloom right over the bolt, so it is very easy to get it in wrong. Torqued it, and while I swapped #2 and #4, the code didn't happen on #2, and when I checked the coilpack with a DMM it looked right. A transistor on the primary, and a diode attached to the coil on the secondary side. Someone (likely not them) foo-barred the bolts for the plastic cover as well all 4 were junk, which was the result of a second thread insert in the composite valve cover being bad. Take the cover off a number of times,. and that bad insert jacks up the bolt. Those bolts are ridiculous expensive though, for a NON-Structural bold. $8 a piece. You can likely get away with allen key M6 bolts and washers from HomeDepot or other places in the right length. They should NOT be longer, you'll possibly crack the valve cover! Lesson: Check the bolts for damage when you take them out, and hand tighten them. IF ANY early resistance CHECK! Hadn't I been able to fix the thread, this would have been a valve cover... Which Nissan wants ~260USD for (+ gasket). There are way cheaper ones on Amazon, but I didn't trust them.
I have a 09 Murano. And I took the back plastic plenum off one day. And you should have seen all the lost screws and junk that was just sitting were the injectors are.. Lol I swear every hole of my engine has a screw in it now. 😂
I have 2005 Nissan Quest . Recently Replaced plugs, coil pacs, o2 sensors, cam shaft and crankshaft position sensors. Vehicle has 240,000 miles on it. It runs fine until it gets temp up... 15 or 20 miles, then engine quits. It will not start until it sets for 15 or 20 minutes then starts and runs fine . No fire from coil pac. ???? Any help?
Will this work on a 2003 Nissan murano? Also do I have to remove everything you did to only replace coil #5? I also need to change o2 sensors, should I consider doing it at the same time ?
Same here.. Code P0305 on my 2003 Murano. Ive heard yiu can replace coil for #5 without re installing removing plenum - still havent heard from anyone that did it!
Yeah, well the great thing was that my code was p0305. Amazingly, the 5th cylinder was almost inaccessible in my 04 Altima, but with a u-joint and a ratchet and some nimble fingers i was able to pull out the coil and plugs. If it was Cylinder 1 or 3, I would have had to go through this. Turned out it was just a failing spark plug. A $10 fix. Got my car back on the road and running well. Hopefully the other 2 sparks in the back don't fail in the near future, if they do, I ll be back on this page.
@@ultimatenoob3 hey..I know you posted this about 2 years ago... Im guessing you had the V6 Altima ? I have a code P0305-Cylinder 5 on my Murano and want to see if I can do this without removal of Intake Plenum..Did you remove Airbox though?
@@happyseany nope. Just used a ratcheting driver with a universal joint couple to go around the bend to loosen the bolts and the spark. To pull out the plug you can use a magnet or what i did was a small 3/4 inch pipe section with some rubber band on its end to grasp the spark plug and pull it out the chamber. Never needed to pull out the airbox or anything. took about 30 minutes. Funny thing is 5 months later on cylinder 3 misfired. And I ended up pulling out the plenum anyways and replaced all the plugs. For me it was actually the spark plugs that were the issue not the coils.
@@ultimatenoob3 Hey - thanks so much man for the tips! going at it this Friday. I did all the plugs, valve cover and Coil # 1,3,5 about 2 years ago with all Nissan parts - and getting friggin' Code P0305 - I feel like I did my time and don't deserve this crap! Took out intake manifold/plenum.. windshield wiper arms, motor, cowling...blah blah blah ... and still got a code with only 12k miles since all that work!! So pissed. But I will definitely try what you said and to grab spark plug and I have a 1/4" drive u-joint. Wish me luck! Thanks for quick reply!!
I'm almost certain that the designers of the engine at some point wer in a meeting with the bosses during the development stages, there had to be at least one or two that said, "what about when it's time to change the spark plugs, isn't it going to be he'll to do that?", the rest of the guys in there probly said, "shhhh! Shut up man! Who cares about that! We'll be long gone by the time they start complaining." And so then they just left it like that and said "f**k it".
Question: The factory manual tells me to drain the coolant before removing the plenum. Do you think this is necessary? If not, why? I don't want to drain the coolant if it isn't necessary. I have a 2005 Nissan Maxima.
You don't need to drain the coolant as I have done in the video. The reason the factory manual mentions draining the coolant is because it includes steps to disconnecting the throttle body which has coolant lines. And the throttle body is attached to the plenum, but you only need to move the throttle body to a side when working on this.
I replaced all the coul packs an sensors an now the car has a red light on dash of a car with a key inside it the security light an will not start up it turns over but wont fire up it's like it's in secure mode what do I do I done the hard factory reset I dont no wat to do 06 Nissan murano
Disconnect the battery for about a half hour...that should reset your computer. Also try changing the battery in your key fob. Hope it works out for you.
@@thatmexican7317 hey man I ended up had it taken to dealer there saying thet there isn't any readings of 5v coming in to the immobilzer so they think I should buy a new key an reprogram it bc everything else seems fine so I dunno
Hey for the record I put in some carburetor cleaner I mean fuel injector cleaner ran two tanks of high-test away which I always run and the cold went away and started running better
It depends on the mileage you have on the spark plug. Even though they are 100k mile plugs, lets say if they are 70k or 80k on them, you can replace it.
went to canadian tire and told them i scanned my nissan and got a p0303 they suggested a spark plug, coil and plenum gasket replacement. Was charged 509 but when i got the car back the problem was worst, now i get p0300 multiple misfires. So i went back to them and tehy want to charge an extra 100 diagnostic because they say I requested the work done and not a diagnostic. so I agreed with the rep i spoke to who suggested what to repair. Gave in and OKed the diagnostic but now they are still waiting for a diagnostic because they cant figure oiut whats wrong. It is going on 3 days now. What could be the problem since they replaced the parts that would cause this problem?
dude. that's awesome video. I messaged before about your quest. I also have a 2004 quest se. I have the misfire #3 plug etc. and lcd screen issue and ops I believe my timing chain finally went bad. now its at my mommys house sitting there . I guess its the old car blues but the quest drives fine and I do like my big girl but Money ways . she costly. and misses need a car. driving aunts car for now. keep the good work up
The Nissan 3.5 V6 is a good engine, but problems can occur with high mileage if not cared for. Also working on it is not the easiest. Thanks for your comment!
The PCV is on the rear valve cover. If you buy a replacement valve cover from NIssan, it comes with a new PCV already installed. I already replaced that valve cover along with the PCV before doing the front.
dial2fast I used an aftermarket valve cover for the rear and I regret it. I was just wondering if I can access the pcv valve without removing the Platinum?
Awesome, except did change all spark plugs, and coils ran okay for a while, started shaking again. Just did #3 again ran okay for 80 miles, started shaking again. Any suggestions!
I see. Were they all the same type? If I didn't know the person or previous history I like to change them all at once. I despise these Nissan valve covers....I started to go towards Honda/Acura over the years. Both my Nissans "2006's" have had major issues no thanks to design flaws from Nissan :(
I had 2012 maxima automatic, engine service code show cylinder 6 misfire, can you tell me where is the # 6 locate at, and what do you call that gas ket
On the Maxima, #6 should be the front spark plug (close to radiator) last one on the driver's side. Looking at the engine while standing in front of the car, the rear 3 plugs from left to right is 1, 3, 5. The front plugs are 2, 4, 6.
I have an issue and I'm hoping someone can help. Initial issues is the pesky PO174..catalyst efficiency below threshold bank 2. I purchased just 2 catalytic converters along with 2 o2 sensors. Took to Nissan to fix. They failed me. Code is still 🔥. Spent 3 grand. I provided parts. Cost is labor. Provided I had other stuff done like, struts and 1 wheel bearing. Picked up my car after 8 days in the shop. All suspension stuff came out ok. Just a bit of a noise now. Abs, slip and ATC OFF LIGHT all display on screen. HELP! CEL.
number five is far back right near throttle body when facing front of car underneath intake manifold. Firing order/location 1,3,5 left to right cylinder under manifold and 2,4,6 left to right at front of engine near radiator.
hello dial2fast.i have a question about this kind a job will cost in a shop to fixed, because I have a 07 quest se, showing the same code, if u can give idea with labor and parts,thank u
I have same problem, 3th piston. I changed the ignition coil last month and today it went bad again... before i change it all over again can someone tell me what might be causing same coil going bad? It was a cheap coil, can it be simply because of that or can it be something else, something i should check while its open. I have changed the spark plug as well btw
With the coil, only use Nissan OEM part. They are more expensive but considering the work involved to replace the back one, you want to only do it once.
@@apache08 A coil pack is an electronic device, and aftermarket coil packs may use cheaper components which can lead to premature failure. Thus the lower cost.
Thanks for the video. I would recommend putting a large rag over the intake once the plenum is removed. You do not want to drop a bolt or anything else in the intake.

Too much damn work just to change the plugs and coils because some nimrods in engineering and/or beancounters in accounting couldn't give the vehicle an intake manifold that's easy to remove for servicing the engine on the side with the odd-numbered cylinder bank.
Another post here said that the owner got a quote from a shop for $700 to do the work. That's not far off the mark for the labor plus parts.
I have the same problem that u mentioned so now I think it is my coil packs because all three is black and probably the ones in the back are too and I'm going to replace all of them thanks for showing me the problem in your video I needed that truly
I like that you went ahead and replaced other things just because!
I don't understand why only one plug was replaced. They are cheap, compared to the coils.
Great video I'm in the middle of doing my tune up going to change valve covers and coil while I'm back there I also did my front struts figured with the cowl off might as well.Thanks again for the great video's and advice.
Ray, I'm buying front struts for my 2004 Nissan Maxima 3.5. I recently watched a vid about how to uninstall and install new ones. The dude didn't show removing the cowl. Am I missing something here?
Replacing Ignition Coils : Step 1 - Remove windshield wipers.
It just seems so wrong to me !
But there it is !
I never would have believed it.........
Thanks.
Out of curiosity, how long did it take you to do the whold thing? I imagine just taking apart the window cowl and plenum feels like 2 hours alone.
At any rate, I am happy your vids exist. Thank you very much.
Great info. It was exactly my problem. The layout was a bit different what you described but the solution was the same. The coil that was bad on my 02 Pathfinder took 20 minutes to remove and replace. Thank You.
The music in your video is so soothing it makes me feel like my problem isn't all that bad.. 😄
I have a 2002 Nissan Maxima SE 56,000 miles 19 years old never had a spark plug change in it's life, started misfiring check engine light on, took it to the Nissan dealership they installed 6 new spark plugs 6 new coil packs, a rocker panel and the gasket paid $2685 more than the cars even worth but I gotta say it runs like a top lol
A misfire can also happen from loss of compression in the cylinder (bent or broken valves). It would be better to do a compression test before replacing the coils. Because you might have spent time and money and still have a misfire.
Hard to do a compression test when you can't get to it.
Great video. Clear, concise, and helpful. Thanks!
Just had my 2010 Honda Odyssey do the same thing last month. Immediately brought it back to the Honda dealership and told me that there was a class action settlement that resulted in compensation for repair and warranty extension for this particular issue. Honda changed out the required parts and changed all spark plugs. I have a link if you're interested in regards to the class action suit since you have the same honda vehicle.
It doesnt apply to him because he has the EX without VCM
Excellent video. Im about to starting working on my quest. I have the same problem. Keep up the good work!!
Thank you for tye great video. It was the first and only time I changed that particular piece. Your video helped tremendously. Thanks again
It's a good idea to replace the $10 PCV Valve any time the intake plenum has to be removed...
That thing ain't $10 dollars with this engine, closer between $30 and $40, but I still agree with you.
Many thanks brother. Your videos are amazing. Great job👍
Thanks for all Quest series videos You share with Us , I have a 2004 quest and was my time for this misfire P0303. For same reason which I don't know My quest was working ok when I was turnin on the A/C. sound crazy but happened to my quest , so I purchase one Ancel which shown P1800 $10 parts easy fix... I was so happy , but after 5 miles driving P0303 come back and this time A/C was not able to stop that P0303, so I started all what you did plus I ordered all those Nissan parts for the replacement and after all that work to be done and right, I Started my Quest and got P0301 and after while (2 minutes I guess) P0300 ..... Any Idea what can go wrong ?
I'm trying to figure what is wrong
Thanks again.
Been following you for a minute, and you always have great content. I have a p0300 code, which you explained at the end of your video was the last number represented the cylinder. P0300 I'm lost trying to trouble shoot which cylinder. Any idea? I have a 2006 maxima with 218,000 miles, and I'm thinking more towards the catalytic converter.
You probably already googled it, but P0300 indicates that two or more cylinders are experiencing misfires. You might want to take it to a mechanic to have them troubleshoot it since it's multiple cylinder having issues. If you want to tackle it yourself, you can first try replacing all 3 coil packs and spark plugs on the front side, and see if that fixes it (since the front side can be replaced easier). If that doesn't fix it, then do the back 3. Also the plugs need to be replaced every 100k miles anyways.
very helpful and informative as the same problem with my nissan quest 2004. thank you very much.
I just change my coil pack, put new spark plugs because it had po303 code, it needed them change, great videos, done all that work, still driving the same way, they said it could be fuel filter now, do you have a video on changing it
thanks for this magnificent video, I found the solution the bad thing is that it is cylinder 5 so I have to do all the work.
Awesome video...How long did this #3 repair take you ?
About 3 hours.
one of the best video ever seen. Thank you. I have the same problem bud in Cylinder #1 P0301.
Victor Martinez how do you know which coil pack is bad?
These engines have a problem burning up ignition coils, inspect your battery ground cable, it probably goes down to the firewall and then down to the transmission, it likes to break at this point and the large current produced by the coil has no way to go to a good ground so they burn up one or more coils. Give yours an inspection and as preventive maintenance add a redundant grounding kit similar to what the HIFI audio guys do. Do not bolt to plastic intakes or similar areas.
No need to remove anything but the upper plenum in order to change #3 and #5. I changed the pack on #3 two days age in just over an hour. #1 does require both upper and lower intakes to be removed.
Hello, Did you remove the window cowl and wipers to get to it? Thinking of doing myself and that may determine if I do or not? Thanks
Great video. Do you think that this is similar to a 2006 nissan maxima, US? i have a p0301, cylinder 1 misfire. car has a bit over 200k miles . Spark plugs are almost 3 years old, and maybe 20k miles. I also just had the firewall pre-cat replaced. Thanks!
The repair process will be the same for your car. If you are getting the P0301, then it appears to be a bad ignition coil, but I can't guarantee you that over the internet. Just make sure you buy original Nissan part for this repair.
Thank you for the reply. You used a torque wrench for the intake manifold. Is it necessary or could i get away with just a regular wrench? thanks!
You really should use a torque wrench so the entire piece is torque down evenly so it's not too loose for leak or too tight to warp the part.
I don't speak english.
I see video
Thanks.
No entiendo inglés, pero vi el video
Gracias. Good lock
Thanks for the video. Merci beaucoup pour la vidéo
Where u located?. I need the same repair done on my 2004 Nissan Quest V6 3.5L SE
Thank you for sharing your videos. This is really helpful! By any chance do you have a link to the service manual for the 2008 Nissan Quest? I have not been able to find one. The best I can tell is that it might be the same manual for the Mercury Villager?
Try this www.nicoclub.com/nissan-service-manuals
Outstanding video! My 2004 Altima, also with the V6, looks identical under the hood.
P0306 so... LUCKY me!
I have a 2005 nissan quest.
My issues is I have no power going up hills and as I press for more power the engine starts knocking so I let off gas real quick.
It also.could be spark knock.
I'm also having extended crank issues. It's starts but only after it cranks for about 5 seconds or so.
BTW I am get backfire as well when I gun it to get more speed
Great video, just curious to know if a Check engine light came on for bad coils? My car is hesitant from 2700 RPM to 3300 RPM and a lot of people say it's the coil packs but I have no check engine light
Even if you have no check engine light, you can still plug a scanner to it and check for any pending codes.
misfire are caused by low compression foul spark plug bad ignition coil and loose injector and coil wire connector what if you change the coil for p 0303 and the cylinder compression was low or injector 3 connector is loose half way down the road the check engine light will come back on
for p
0303
That's where I'm at. I replaced all coils, plugs, vacuum lines, and air filter. Still have the code that wont die. P0303
Do a compression test on all cylinders also you might carbon deposit on the intake or exhaust valve that can cause a compression leak when it is on the compression stroke causing pressure to leak which can cause a missfire.
Should have replace all the plugs and coils at the same time. My cousin had a similar issue with a Ford Taurus, he only replaced the plugs in the back and the coil pack, this is a single pack for all cylinders. Ran great for 2 days then died. He found out that all the plugs, coil, and the wires also, should have been replaced at the same time. It ended up creating an electrical imbalance between the cylinders. The ECU couldn't handle it and it burnt out the coil pack. He replaced it all and hasn't had a problem since. I am having a miss on cylinder 5 of my Maxima. I am replacing all plugs and coils at the same time. Just saying would hate to ruin the 3 three coils in the back and have to replace them again. And it is good insurance to make the motor as efficient as possible. Later.
Great video. Do you have to apply an RTV on the plenum gasket? Thanks.
No RTV on the plenum gasket.
My wife's car has a similar problem, but luckily it's P0304... It has a 130K miles, so others are possibly a problem, but I think I'll stick for now with just the front center one, which should be an easy one to do right now.
I have the same code P0304 in my 03 nissan murano 🤠🔧🔩
@@franxiscofajardo2063, that is the front center cylinder. I have ordered a Delphi Gn10242 oe coil pack from amazon. Totally affordable for a Japan made piece...
@@thinking-laaf
I already fix it, it take me 10 minutes to fix it I had saved a coil from my nissan 350z I put in on and the problem was over 👍. Good luck with you car 😎
So. Ok. The problem was simpler than expected. Makes me slightly peeved about the mechanics which replaced the spark plugs at 100K though.
They potentially / likely misthreaded the #4 coilpack bolt and it potentially wasn't tight enough. There was play up and down for the coilpack when I swapped #2 and #4 (didn't notice it when I took the bolt out :-( ). I had to clean up that thread with an M6 tap and voila, the bolt went in by hand almost all the way. (I was very concerned NOT to go too deep with the pointy tap..., made sure I had at least 3-5mm clearance from the bottom of the hole - I checked with a gauge, and taped the tap off so it wouldn't go too deep... - used air to blow out the parts and oil to make sure that wouldn't cause problems, and checked the holes with a light. This 2007 Murano (In your video it's different) has a 1" wireloom right over the bolt, so it is very easy to get it in wrong. Torqued it, and while I swapped #2 and #4, the code didn't happen on #2, and when I checked the coilpack with a DMM it looked right. A transistor on the primary, and a diode attached to the coil on the secondary side.
Someone (likely not them) foo-barred the bolts for the plastic cover as well all 4 were junk, which was the result of a second thread insert in the composite valve cover being bad. Take the cover off a number of times,. and that bad insert jacks up the bolt. Those bolts are ridiculous expensive though, for a NON-Structural bold. $8 a piece. You can likely get away with allen key M6 bolts and washers from HomeDepot or other places in the right length. They should NOT be longer, you'll possibly crack the valve cover!
Lesson: Check the bolts for damage when you take them out, and hand tighten them. IF ANY early resistance CHECK! Hadn't I been able to fix the thread, this would have been a valve cover... Which Nissan wants ~260USD for (+ gasket). There are way cheaper ones on Amazon, but I didn't trust them.
Very good video help me a lot I got a Nissan quest 2004 👍
I have a 09 Murano. And I took the back plastic plenum off one day. And you should have seen all the lost screws and junk that was just sitting were the injectors are.. Lol I swear every hole of my engine has a screw in it now. 😂
Did you replace all 3 coils as well?
What gaskets did you replace, and why do you have to replace them?
I have 2005 Nissan Quest . Recently Replaced plugs, coil pacs, o2 sensors, cam shaft and crankshaft position sensors. Vehicle has 240,000 miles on it. It runs fine until it gets temp up... 15 or 20 miles, then engine quits. It will not start until it sets for 15 or 20 minutes then starts and runs fine . No fire from coil pac. ???? Any help?
Awesome great video couldn't be any better...Thank you
Will this work on a 2003 Nissan murano? Also do I have to remove everything you did to only replace coil #5? I also need to change o2 sensors, should I consider doing it at the same time ?
Byron Argueta did you ever find out I have the same code and problems as you ? Would be helpful if you could reply back thanks.
Same here.. Code P0305 on my 2003 Murano. Ive heard yiu can replace coil for #5 without re installing removing plenum - still havent heard from anyone that did it!
How long did this repair take you? Im considering doing it myself, and knowing how long it would take would be really beneficial.
If this is your first time and assuming you have all the tools, for the Nissan Quest, it may take around 4-5 hours.
Yeah, well the great thing was that my code was p0305. Amazingly, the 5th cylinder was almost inaccessible in my 04 Altima, but with a u-joint and a ratchet and some nimble fingers i was able to pull out the coil and plugs.
If it was Cylinder 1 or 3, I would have had to go through this.
Turned out it was just a failing spark plug.
A $10 fix.
Got my car back on the road and running well.
Hopefully the other 2 sparks in the back don't fail in the near future, if they do, I ll be back on this page.
@@ultimatenoob3 hey..I know you posted this about 2 years ago... Im guessing you had the V6 Altima ? I have a code P0305-Cylinder 5 on my Murano and want to see if I can do this without removal of Intake Plenum..Did you remove Airbox though?
@@happyseany nope.
Just used a ratcheting driver with a universal joint couple to go around the bend to loosen the bolts and the spark. To pull out the plug you can use a magnet or what i did was a small 3/4 inch pipe section with some rubber band on its end to grasp the spark plug and pull it out the chamber. Never needed to pull out the airbox or anything. took about 30 minutes.
Funny thing is 5 months later on cylinder 3 misfired. And I ended up pulling out the plenum anyways and replaced all the plugs. For me it was actually the spark plugs that were the issue not the coils.
@@ultimatenoob3 Hey - thanks so much man for the tips! going at it this Friday. I did all the plugs, valve cover and Coil # 1,3,5 about 2 years ago with all Nissan parts - and getting friggin' Code P0305 - I feel like I did my time and don't deserve this crap! Took out intake manifold/plenum.. windshield wiper arms, motor, cowling...blah blah blah ... and still got a code with only 12k miles since all that work!! So pissed. But I will definitely try what you said and to grab spark plug and I have a 1/4" drive u-joint. Wish me luck! Thanks for quick reply!!
I'm almost certain that the designers of the engine at some point wer in a meeting with the bosses during the development stages, there had to be at least one or two that said, "what about when it's time to change the spark plugs, isn't it going to be he'll to do that?", the rest of the guys in there probly said, "shhhh! Shut up man! Who cares about that! We'll be long gone by the time they start complaining." And so then they just left it like that and said "f**k it".
good job...i like your video.
Extremely helpful.
I went to buy the intake gasket but it comes with extra 2 rubber gaskets, what are they for?? Thanks in advance
You're the best 👏👏👏dial2fast
did you replace the gaskets besides the egr valve
Question: The factory manual tells me to drain the coolant before removing the plenum. Do you think this is necessary? If not, why? I don't want to drain the coolant if it isn't necessary. I have a 2005 Nissan Maxima.
You don't need to drain the coolant as I have done in the video. The reason the factory manual mentions draining the coolant is because it includes steps to disconnecting the throttle body which has coolant lines. And the throttle body is attached to the plenum, but you only need to move the throttle body to a side when working on this.
Thank goodness. Thanks for the video & reply.
this is the part number : 22448-8J11C
Was your van shaking on the front? Mine stated shaking like loosing power
Not shaking, just loss of power.
I replaced all the coul packs an sensors an now the car has a red light on dash of a car with a key inside it the security light an will not start up it turns over but wont fire up it's like it's in secure mode what do I do I done the hard factory reset I dont no wat to do 06 Nissan murano
Disconnect the battery for about a half hour...that should reset your computer. Also try changing the battery in your key fob. Hope it works out for you.

What if you're spark plugs are still good do you still have to replace them to
It depends on the mileage you have on the spark plug. Even though they are 100k mile plugs, lets say if they are 70k or 80k on them, you can replace it.
went to canadian tire and told them i scanned my nissan and got a p0303 they suggested a spark plug, coil and plenum gasket replacement. Was charged 509 but when i got the car back the problem was worst, now i get p0300 multiple misfires. So i went back to them and tehy want to charge an extra 100 diagnostic because they say I requested the work done and not a diagnostic. so I agreed with the rep i spoke to who suggested what to repair. Gave in and OKed the diagnostic but now they are still waiting for a diagnostic because they cant figure oiut whats wrong. It is going on 3 days now. What could be the problem since they replaced the parts that would cause this problem?
Did you find the problem?
dude. that's awesome video. I messaged before about your quest. I also have a 2004 quest se. I have the misfire #3 plug etc. and lcd screen issue and ops I believe my timing chain finally went bad. now its at my mommys house sitting there . I guess its the old car blues but the quest drives fine and I do like my big girl but Money ways . she costly. and misses need a car. driving aunts car for now. keep the good work up
The Nissan 3.5 V6 is a good engine, but problems can occur with high mileage if not cared for. Also working on it is not the easiest. Thanks for your comment!
Is cylinder 1 in the front passenger side??? Same 3.5
Super thorough video. And great advise
Have you ever changed the PCV on your vehicle? I believe it sits behind the rear valve cover?
The PCV is on the rear valve cover. If you buy a replacement valve cover from NIssan, it comes with a new PCV already installed. I already replaced that valve cover along with the PCV before doing the front.
dial2fast I used an aftermarket valve cover for the rear and I regret it. I was just wondering if I can access the pcv valve without removing the Platinum?
Great and details video ! Your job is very neat and tidy plus the vehicle too.
Thanks for your comment!
how do i find out on the firewall side of passenger side their are 2 green plugs one going to the coils what dose the outher go to
Please what video camera you used to make this video?

Why didn't you just do all 3 spark plugs since you were back there? Great vid tho!
Because all the spark plugs were replaced several months before this repair.
I see. Were they all the same type? If I didn't know the person or previous history I like to change them all at once. I despise these Nissan valve covers....I started to go towards Honda/Acura over the years. Both my Nissans "2006's" have had major issues no thanks to design flaws from Nissan :(

I have an issue and I'm hoping someone can help. Initial issues is the pesky PO174..catalyst efficiency below threshold bank 2. I purchased just 2 catalytic converters along with 2 o2 sensors. Took to Nissan to fix. They failed me. Code is still 🔥. Spent 3 grand. I provided parts. Cost is labor. Provided I had other stuff done like, struts and 1 wheel bearing. Picked up my car after 8 days in the shop. All suspension stuff came out ok. Just a bit of a noise now. Abs, slip and ATC OFF LIGHT all display on screen. HELP! CEL.

Mine is the same it says multiple cylinder misfire
Where is the 5th cylinder located I got a P0305 misfire that to the front of the engine?
number five is far back right near throttle body when facing front of car underneath intake manifold. Firing order/location 1,3,5 left to right cylinder under manifold and 2,4,6 left to right at front of engine near radiator.

hello dial2fast.i have a question about this kind a job will cost in a shop to fixed, because I have a 07 quest se, showing the same code, if u can give idea with labor and parts,thank u
Depending on how many ignition coil you need to replace. Those are pricey bits. I would say probably $500 - $700.

I have same problem, 3th piston. I changed the ignition coil last month and today it went bad again... before i change it all over again can someone tell me what might be causing same coil going bad? It was a cheap coil, can it be simply because of that or can it be something else, something i should check while its open. I have changed the spark plug as well btw
With the coil, only use Nissan OEM part. They are more expensive but considering the work involved to replace the back one, you want to only do it once.
@@dial2fast thanks for reply, im going to buy nissan this time. Can something causes same coil go bad you think?
@@apache08 A coil pack is an electronic device, and aftermarket coil packs may use cheaper components which can lead to premature failure. Thus the lower cost.
