Check your alternator connector/make sure it’s Grounded! Make sure the power supply line is tight! But the Harness! Check wires! I had to replace my alternator connector, p0300. Solved my problems once and for all…. I swapped out the fuel ⛽️ pump Cleaned injectors/Changed plugs/Coil packs…. Changed fuel rail lines…. Was on my way to changing injectors. While removing my alternator to do my valve cover and Clean my bottom block, ALTERNATOR!!! 🤦🏾♂️ HARNESS
Jus curious but why is it necessary to install the coil packs back in the same cylinder? Never worried about this with my past vehicles & didn't have any problems. Only the coil pack connectors have to go back to the same cylinders.
Lol yeah man i agree with the other guy. You are a huge help. Singlehandedly have kept my car running and kept me from getting a 370z. 10/10 for content.
That’s a fact I had a hole week dealing with a misfire! Then I watched your video and the part you show to keep the coil cables separate, I was mixing 2 of my cables without even noticing. I watched your video and went straight to the problem big help ✊🏾💪🏾
If these go bad can you get the code P2A00??? Please let me know cause the code keeps coming back and after clearing it runs fine but later it comes back after an 1hr
Hey man I have a quck question my g37 sedan is throwing code P0300 I replaced the dork plugs and when I turned it on and rev it once it hits 2500 rpm the car starts to jerk and idk what else to check I’m new to this Infiniti stuff would appreciate the help
Bro u know what sucks I changed both and still got the miss fire and the horrible code, i wish the computer was more specific 😅 but it gotta be random ig
Things go wrong with these cars they're old, but the good thing is they happen one after another so you get to know your car and slowly upgrade it. They are old cars but they will last a very long time and look and run nice. Its worth the repairs. Everything can be done yourself just research and study the repair manual, don't pay the dealership they will triple the price and you can fix so many things for the price of one job at the dealership. Spark plug change is 368$ at nissan here i did my ball joints, belt, and plugs waaay under that price. Ball joints alone 1279$ and it only costs 72$ to diy.
Motordyne G35 Thanks for the video brother I've had my G for less than 2 months and it started acted up and shot a p0305 code. Changed out all my spark plugs and ignition coils after watching your video it was a breeze. Car runs better than when I bought it now!

my car is having a misfire right now and a reader told me it was the 2nd cylinder. i changed the spark plug on it but didnt change the coil and im still having misfires. i also had a cam shaft bank 2 sensor on so i went ahead and replaced that too but my car is still misfiring. what should i do ? should i replace the coil aswell ?
@@sneakerguy2430 did you use a reader? If you don’t have one, just go to auto one or orielys. Ask for their reader. It should tell you what cylinder is misfiring . Once you find out which cylinder, change that coil. Or if you want you can change all 6 coils. Your choise

Hey bro. G owner here. I have an 03’ and it was shaking extremely badly at idle and misfiring like a bitch , so me and my buddy changed the spark plugs and ignition coils and it still misfires extremely bad. The check engine light flashes. After I did the spark plugs and ignition coils I put sea foam in it to help clean the fuel injectors. It’s STILL misfiring after those 3 things I did to the car.

Yeah the vq with a misfire shakes like a diesel truck. How many miles do you have? Check out my other video on bleeding the radiator. It only takes 1 time overheating to blow a head gasket. It will sound like a gunshot so you will know if you blow it.
Motordyne G35 it’s berly about to hit 130k miles, it started shaking a little bit and stopped after a min but I’m going to do these steps and the radiator and clean the fuel pump and hopefully it drives smooth, I only purchased the spark plugs sound I get the plugs also ? And what is the best spark plugs and plugs to purchase ?
@@MotordyneG35 currently 225,000 approximately I don't know exactly because it's at my grandfathers shop. I use his shop because he has pneumatic tools and other miscellaneous tools I don't have Edit:also my vq was smoking really badly at the end
@@mf7338 ....225k is still up there in mileage, can't really complain, the G was definitely driven. 250k-300k is all you can expect with perfect maintenance. I am at 180k miles currently.
Yes. P0300 means more than 1 cylinder is randomly misfiring. For example, p0303 means cylinder 3 is actually misfiring. It is best to replace it all, it is time once you get the code.
Lifetime warranty from Orileys, if they ever fail you keep getting a new set for free. Most people don't keep a car longer than 3 or 5 years. Going on 14 years with the G with almost all of my parts from Oriley's because of the lifetime warranty. If it has a lifetime warranty I buy from Oriley's. No warranty, I use OEM. Import direct is the brand of the ignition coils.
@@MotordyneG35 ahh I was Looking at some Right now I was thinking of going with bwd but I'm planning on doing a tune on my car soon. I know you have a tune on your that's why I was curious on which brand you used
Yes, it's the same. I go over why they come pre-gapped at.044 and even though the service manual says .043 is the gap, no need to try to move .044 to .0443, that is close enough; so they are pre-gapped. Not every spark plug is pre-gapped for every car......ua-cam.com/video/j5WhqWPoLTk/v-deo.html
Hey man I changed a my intake plenum gaskets and valve cover gasket and covers but I accidentally over tightented 4th cylinder ignition coil and now it's just spinning when I try to loosen it how would I remove that
@motordyne_g35 I watched the vid and I was trying to listen to which spark plug PLFR5A-11 or PLFR6A-11 you went with in the vid but I couldn't catch it. Could you let us know. thanks for the great info!!!
I've been through this before, I stopped it before the Misfire Random P0300 code came. It will go months with random stalls and dying before you get the code. After inspecting the plugs, multiple plugs were out of gap spec which is .043. Out of the 6 plugs, 2 were way off at .055 gap. Cylinder 6 and 3 I believe were the 2 way off the most. I had not actually gotten a misfire code yet, just the car dying at idle randomly. I even did my own idle relearn video and changed out my air filter hoping that was it, nope. I knew it was time again to do this job. Car runs perfect again now and much better.
The electrical grease should only be used on the tail of the plug because it conducts current. If it's all the way down the side of the non condition ceramic it can cause spark jump to the ground/threaded side of the plug and cause misfire codes as well.
Replace Coil packs, Replace all 6 get the good ones it’ll cost roughly $200-$300 for all 6 but you won’t have to worry about replacing them for awhile. You should always replace Coils with Spark Plugs.
My 350z hesitated when i hit the gas on the highway i changed my spark plugs and it stopped. The throttle response is instant now. Now i have to get a new radiator because its leaking lol
For some reason, my check engine light would come on asking to replace coolant temp sensor but i already replaced it. After a few weeks of it being on, it goes away. This keeps happening. Anyone have an idea? Thanks.
Man I’ve been wanting to do this lately ! Thanks for the informative vid man. So G is so nice ! Wish I could afford that exhaust and suspension:( I’m only 17 and got a straight pipe and lowering springs 😂
Hey could you help me out? Got code P1168 last night for closed loop control bank 2. I just want to confirm this is the driver side O2 sensor?.. Thanks buddy!
Do you have to replace coil packs with OEM? I followed your video step by step. Changed out plugs with same ones and changed coil packs. Now I have hard shifting occurring sometimes. My G35 only has 34k miles.
Import direct is which brand from Oriley's. Cost me $0 to replace. Lifetime warranty. OEM doesn't offer any warranty and they both will only last 50,000 miles is why I never bought OEM. www.oreillyauto.com/detail/b/import-direct-ignition-4489/ignition---tune-up-16776/ignition-coils-19690/ignition-coil-12493/90c5da72ae86/import-direct-ignition-coil/230249/5732200/2005/infiniti/g35?q=Ignition+Coil&pos=1
It would have been smarter to make the coil connector cables varying lengths pending on the position of each cylinder. That way you’ll not mix up the cables.
Perfect timing, doing this today! My coils are not coming out in one piece so I picked some up from advanced and some ngk plugs the 5s not the 6s although I should have grabbed the 6. Thank you for posting this! Lol Edit: Have you replaced your oil pan gasket? Mine is leaking really bad when I go fast and it smells like burnt oil. Just wondering if it is Just the gasket on the pan doing that? It looks like it sprayed out.. I'm getting the new one today.
Yeah don't buy off ebay, the half price spark plugs have to be fake. UA-cam videos proving it. I also went to the parts store to not risk it. The 6's? Are talking about 1 step colder spark plugs? PLFR5A-11 - Factory Heat Range (5) is best for vehicles without any modifications PLFR6A-11 - One Step Colder (6) is best to be used when any engine modifications have been done (Including air intake, exhaust, etc.) Yeah, I should have also gone with the 6's. I went with OEM PLFR5A-11 heat range, Iridium IX though. I completly forgot about 1 step colder, oh well they are already installed now and it runs much better. The random stalling went away. The gap was way over too on the used plugs. www.z1motorsports.com/ignition-system/nissan/oem-vq35de-spark-plug-ngk-plfr6a-11-p-3187.html
@@MotordyneG35 Awesome! Thanks for the link and prompt reply, I appreciate it. Those are cheaper than I paid, picked mine up from advanced and they were 14 a piece. Yes, I was talking about the one step colder plugs haha. It's raining at the moment so slightly gridlocked as I do not have a garage🙄. I love your vids and your G. Can't wait to get my Motordyne ART pipes and shockwave exhaust
Is the hesitation you're speaking of when your try and floor it and the engine kinda does this whole pause thing before it finally begins to accelerate? I hate that and I'm not sure how to get rid of it.
I don't mean when your driving and floor it, I mean from a stand still. Like I press the gas and it tries to go full throttle, then it stops for a second then restarts the acceleration process
Cylinder 6 is most common to have oil in it first before a new valve cover is needed. When I pulled the spark plug out, you can see there is no oil and also down inside the tube there was no oil. The gopro on the gimbal couldn't fit over there to get a really good view. I was also worried about cylinder 6 because I did not feel like doing another valve cover job.
Hey anybody I have a 2007 Nissan Murano with 193,000 miles and I was just doing preventive maintenance by changing the valve covers because when I changed the spark plugs at 170,000 miles one spark plug was covered in oil the ceramic and where it sparks at and changed the 3 rear ignition coils but anyways this week I replaced the valve covers front and rear and that took me 4 days since it’s very cold in Chicago and it was snowing and so when I was working on the front one I had the front ignition coils in a drawer and they were kind of getting snowed on so I just wiped them off and closed the dresser to dry them and install them tomorrow so when I put the car back together I had a code that read P0081 then I looked around the engine and I just reconnected a harness and I reset the code then it was running fine for 30 seconds then it got to running rough again and got a code P0300 and wonder if it’s the front ignition coils but I replaced all the spark plugs at 170,000 miles and only the rear 3 ignition coils
RzVids just look up any forums and learn how to use a torque wrench. It does not get anymore complicated and if you don’t know how to use a torque wrench then you probably shouldn’t be working on your own car

One place said it was a vacuum cap. Didn't fix much. Dealership said it was a P03000 code and their computer couldn't pinpoint the issue. Would swapping out spark plugs fix this? (2005 G35 6MT, 96k miles)
You have a vacuum leak somewhere after changing the plenum spacer.
my car is having a misfire right now and a reader told me it was the 2nd cylinder. i changed the spark plug on it but didnt change the coil and im still having misfires. i also had a cam shaft bank 2 sensor on so i went ahead and replaced that too but my car is still misfiring. what should i do ? should i replace the coil aswell ?
Im having the same problem, I changed the spark plugs and nothing. Mines an automatic and when I start it up it sounds like a rotary .
@@sneakerguy2430 could be misfiring. Did you change the ignition coils?
@@xqxc i haven't, I changed the coil 1 with the second but it still sounded the same
@@sneakerguy2430 did you use a reader? If you don’t have one, just go to auto one or orielys. Ask for their reader. It should tell you what cylinder is misfiring . Once you find out which cylinder, change that coil. Or if you want you can change all 6 coils. Your choise
@@xqxc I've had p0300
Po301 .
Soo you don't have the hitachi one ? Everyone recommends me those
Paul Anthony ....hitachi doesn’t offer any warranty, one fails you buy a new one. I go with the lifetime warranty parts. Free replacement if it ever fails.
Ohhh thats good 😂 didn't see it that way
Have a 06 g35 sedan getting a p0300 code changed all spark plugs and even got all brand new oem coil packs still getting misfire, anybody have any advice?
Did you ever figure it out? That’s where I’m sitting at right now with the same issue
@@jonathanpadilla3149 I ended up changing my catalytic converters and it fixed it for me.
@@RondosRaw damn how much you pay? I probably gotta do the same.
@@GeraldK cats were about $400 for both put them on myself.
@@RondosRaw Where are you get them from?
Soon as you pull it out, stick the nut back in. Best advice I've ever taken 😃
All I have is an Intake and a straight pipe Y pipe, should I get the cold Spark Plugs?
U did great bro 😎
Hey bro. G owner here. I have an 03’ and it was shaking extremely badly at idle and misfiring like a bitch , so me and my buddy changed the spark plugs and ignition coils and it still misfires extremely bad. The check engine light flashes. After I did the spark plugs and ignition coils I put sea foam in it to help clean the fuel injectors. It’s STILL misfiring after those 3 things I did to the car. Any idea what it is ? I’m at a complete loss and confused as hell. Thanx if you do get back to me !
Zakk
Same exact story how did u fix !!!!!!!!!
@@AR_BSME Did you ever get your issue resolved?
My problem also.. gonna change the pcv valve
@Zakk hey did you ever resolve
Man how much coil packs cost i have a 2007 g35s
My 370z got 38,000 miles and I just changed the spark plugs to autolight from auto zone. And now it spudering like 10 times a min for just the first 2 min then it goes away. Guess I'm taking them back and getting denso like it comes with
really good video dude....your the best!!!!
I have 07 g35 I recently left the car turned on but not running for 6 hours and then I noticed and turned it off battery died I recharged it because it was already dead on me already from siting and the gas meter stayed below the line we’re it shows it empty and I have pumped gas and unplugged the negative but it’s still hasn’t shown how much gas I have, now the service engine light turned on after I was in the car with the air on for 1 hour and I turned it off after the temperature went up and when I tried turning it on it started shaking read the code with obdII and it was p0300 code I’m going to change the spark plugs soon and clean the air filter has fresh oil change and berly gets driven it also had p0462 code any help id appreciate it
Yeah the vq with a misfire shakes like a diesel truck. How many miles do you have? Check out my other video on bleeding the radiator. It only takes 1 time overheating to blow a head gasket. It will sound like a gunshot so you will know if you blow it.
Motordyne G35 it’s berly about to hit 130k miles, it started shaking a little bit and stopped after a min but I’m going to do these steps and the radiator and clean the fuel pump and hopefully it drives smooth, I only purchased the spark plugs sound I get the plugs also ? And what is the best spark plugs and plugs to purchase ?
Motordyne G35 you should do video on how to get disc for the navigation mine was broken and need replace it but I can’t find it
@@MotordyneG35 oh no. Not a gunshot. SMH. My car ran hot but that didn’t happen. I hope i didn’t blow a gasket or nun 🙏🏿🙏🏿
I had the same problem with mine, but it was the one of the piston rings where worn out completely so im rebuilding it currently
damn....that sucks! How many miles on that piston ring?
@@MotordyneG35 currently 225,000 approximately I don't know exactly because it's at my grandfathers shop. I use his shop because he has pneumatic tools and other miscellaneous tools I don't have
Edit:also my vq was smoking really badly at the end
@@mf7338 ....225k is still up there in mileage, can't really complain, the G was definitely driven. 250k-300k is all you can expect with perfect maintenance. I am at 180k miles currently.
So this will fix a P0300 misfire code and is this what causes a P0300 misfire code?
Yes. P0300 means more than 1 cylinder is randomly misfiring. For example, p0303 means cylinder 3 is actually misfiring. It is best to replace it all, it is time once you get the code.
@@MotordyneG35 i got the same code p0300 but i change the coils and the spark plugs and still have a misfire you thinks is a bad fuel injector
Drop down into the cylinder?? Coils only good for 50k?? What am I missing here, it’s April fools day or something??
What brand ignition coil do you use ?
Lifetime warranty from Orileys, if they ever fail you keep getting a new set for free. Most people don't keep a car longer than 3 or 5 years. Going on 14 years with the G with almost all of my parts from Oriley's because of the lifetime warranty. If it has a lifetime warranty I buy from Oriley's. No warranty, I use OEM.
Import direct is the brand of the ignition coils.
@@MotordyneG35 ahh I was Looking at some Right now I was thinking of going with bwd but I'm planning on doing a tune on my car soon. I know you have a tune on your that's why I was curious on which brand you used
@@MotordyneG35 How long have these Oreily coils lasted you before?
Your video gives just the right amount of detail. Thank you for taking the time to share with us.
Awesome vid.
Is the De Aand hr vq"s plugs gap is the same? Cause my ngki was gaped to .44 i have the de rwd automatic
Yes, it's the same. I go over why they come pre-gapped at.044 and even though the service manual says .043 is the gap, no need to try to move .044 to .0443, that is close enough; so they are pre-gapped. Not every spark plug is pre-gapped for every car......ua-cam.com/video/j5WhqWPoLTk/v-deo.html
Dont use a q-tip for putting on the grease, micro hairs will get in there.
Hey man I changed a my intake plenum gaskets and valve cover gasket and covers but I accidentally over tightented 4th cylinder ignition coil and now it's just spinning when I try to loosen it how would I remove that
Its doesn't matter which ignition pack goes first just make sure that the connected matches right?
Correct.
This helped alot...thanks man...i wish i had the sockets to do it myself but im getting it done in the morning asap. 👍🏽
You recommend the 6A if it’s modified? Or the 5A?
You making me nervous with all that hand shaking . 😄😄
Def appreciate the content this was a BIG HELP.
@motordyne_g35 I watched the vid and I was trying to listen to which spark plug PLFR5A-11 or PLFR6A-11 you went with in the vid but I couldn't catch it. Could you let us know. thanks for the great info!!!
Can i get the link where you get your spark plugs at?
What brand torque wrench are you using?
So which cylinder was the miss coming from?
I've been through this before, I stopped it before the Misfire Random P0300 code came. It will go months with random stalls and dying before you get the code. After inspecting the plugs, multiple plugs were out of gap spec which is .043. Out of the 6 plugs, 2 were way off at .055 gap. Cylinder 6 and 3 I believe were the 2 way off the most.
I had not actually gotten a misfire code yet, just the car dying at idle randomly. I even did my own idle relearn video and changed out my air filter hoping that was it, nope. I knew it was time again to do this job. Car runs perfect again now and much better.
The electrical grease should only be used on the tail of the plug because it conducts current. If it's all the way down the side of the non condition ceramic it can cause spark jump to the ground/threaded side of the plug and cause misfire codes as well.
Dielectric grease PREVENTS conduction
Good video for the most part, but some of the things said during the video raise a red flag for me...
I just finished doing mine, and it still has sputtering sound
Replace Coil packs, Replace all 6 get the good ones it’ll cost roughly $200-$300 for all 6 but you won’t have to worry about replacing them for awhile. You should always replace Coils with Spark Plugs.
My 350z hesitated when i hit the gas on the highway i changed my spark plugs and it stopped. The throttle response is instant now. Now i have to get a new radiator because its leaking lol
If you have problems bleeding your radiator make sure to check this video out...ua-cam.com/video/o13izIyEI4o/v-deo.html
Did this a few months ago. Passenger side is a BITCH!
For some reason, my check engine light would come on asking to replace coolant temp sensor but i already replaced it. After a few weeks of it being on, it goes away. This keeps happening. Anyone have an idea? Thanks.
Man I’ve been wanting to do this lately ! Thanks for the informative vid man. So G is so nice ! Wish I could afford that exhaust and suspension:( I’m only 17 and got a straight pipe and lowering springs 😂
Focus on the engine , or everything else will sit on the side of the road
Hey could you help me out? Got code P1168 last night for closed loop control bank 2. I just want to confirm this is the driver side O2 sensor?.. Thanks buddy!
What if both change and still missfire
Dead fuel injector.
Spent 2 hours doing this my hands are fucked 😂 very helpful video tho .!!
Do you have to replace coil packs with OEM? I followed your video step by step. Changed out plugs with same ones and changed coil packs. Now I have hard shifting occurring sometimes. My G35 only has 34k miles.
No, the coil packs I used are not OEM. Hard shifting is transmission not engine. Any check engine light?
Can you please add a link on where you bought your coil packs and the price? Is that better than OEM? Thanks

Import direct is which brand from Oriley's. Cost me $0 to replace. Lifetime warranty. OEM doesn't offer any warranty and they both will only last 50,000 miles is why I never bought OEM. www.oreillyauto.com/detail/b/import-direct-ignition-4489/ignition---tune-up-16776/ignition-coils-19690/ignition-coil-12493/90c5da72ae86/import-direct-ignition-coil/230249/5732200/2005/infiniti/g35?q=Ignition+Coil&pos=1
It would have been smarter to make the coil connector cables varying lengths pending on the position of each cylinder. That way you’ll not mix up the cables.
Perfect timing, doing this today! My coils are not coming out in one piece so I picked some up from advanced and some ngk plugs the 5s not the 6s although I should have grabbed the 6. Thank you for posting this! Lol
Edit: Have you replaced your oil pan gasket? Mine is leaking really bad when I go fast and it smells like burnt oil. Just wondering if it is Just the gasket on the pan doing that? It looks like it sprayed out.. I'm getting the new one today.
Yeah don't buy off ebay, the half price spark plugs have to be fake. UA-cam videos proving it. I also went to the parts store to not risk it. The 6's? Are talking about 1 step colder spark plugs?
PLFR5A-11 - Factory Heat Range (5) is best for vehicles without any modifications
PLFR6A-11 - One Step Colder (6) is best to be used when any engine modifications have been done (Including air intake, exhaust, etc.)
Yeah, I should have also gone with the 6's. I went with OEM PLFR5A-11 heat range, Iridium IX though. I completly forgot about 1 step colder, oh well they are already installed now and it runs much better. The random stalling went away. The gap was way over too on the used plugs. www.z1motorsports.com/ignition-system/nissan/oem-vq35de-spark-plug-ngk-plfr6a-11-p-3187.html
@@MotordyneG35 Awesome! Thanks for the link and prompt reply, I appreciate it. Those are cheaper than I paid, picked mine up from advanced and they were 14 a piece. Yes, I was talking about the one step colder plugs haha. It's raining at the moment so slightly gridlocked as I do not have a garage🙄. I love your vids and your G. Can't wait to get my Motordyne ART pipes and shockwave exhaust
Alot of work just to replace the plugs isn't it.jesus christ!
Is the hesitation you're speaking of when your try and floor it and the engine kinda does this whole pause thing before it finally begins to accelerate? I hate that and I'm not sure how to get rid of it.
that is normal. If you are just cruising and hammer it the car drops a gear or two and then goes, which is the lag you feel.
said amir could I reduce our get rid of that?
I don't mean when your driving and floor it, I mean from a stand still. Like I press the gas and it tries to go full throttle, then it stops for a second then restarts the acceleration process
Kyron could be that you’re losing traction it cuts off power then resume happens to me at time. Only way to stop this is get a DCT
said amir ok I'll have to research what a dct is. Thanks
I was patiently waiting for you to pull number 6 and find a whole lotta oil on the plug. That's what happened with me!
Cylinder 6 is most common to have oil in it first before a new valve cover is needed. When I pulled the spark plug out, you can see there is no oil and also down inside the tube there was no oil. The gopro on the gimbal couldn't fit over there to get a really good view. I was also worried about cylinder 6 because I did not feel like doing another valve cover job.
Hey anybody I have a 2007 Nissan Murano with 193,000 miles and I was just doing preventive maintenance by changing the valve covers because when I changed the spark plugs at 170,000 miles one spark plug was covered in oil the ceramic and where it sparks at and changed the 3 rear ignition coils but anyways this week I replaced the valve covers front and rear and that took me 4 days since it’s very cold in Chicago and it was snowing and so when I was working on the front one I had the front ignition coils in a drawer and they were kind of getting snowed on so I just wiped them off and closed the dresser to dry them and install them tomorrow so when I put the car back together I had a code that read P0081 then I looked around the engine and I just reconnected a harness and I reset the code then it was running fine for 30 seconds then it got to running rough again and got a code P0300 and wonder if it’s the front ignition coils but I replaced all the spark plugs at 170,000 miles and only the rear 3 ignition coils
Nice work
Dislike solely for not showing the tightening sequence with torque wrench. I can’t find a video anywhere showing this.
RzVids just look up any forums and learn how to use a torque wrench. It does not get anymore complicated and if you don’t know how to use a torque wrench then you probably shouldn’t be working on your own car
What brand are your coil packs?
