- how to to solve or fix code p0301 p0302 p0303 p0304 on honda vehicules and any other vehicule using live data misfire not the ignition coil pack or spark plug, I fixed it using live data in my scanner step by step
I only came here to see the injector removal because I was chasing the same exact problem. I'm going to bench clean my injectors and see if I solve the issue. I just subbed! great job!
thank you I really apprecia it.
What was the outcome?
This was a perfect diagnosis performed and correctly. Only thing I would recommend. When you swap coils from 1 to 2 you should move spark plug from 1 to 3 to also verify a good plug. 👍 other than that beautiful video.
that is a great idea so the diagnose would be done faster, thank you n stay bless
Lol then fuel injector 1 to 4 😊
What a great job finding out it was the injector that was bad. Thanks for sharing
Thanks for watching! I really appreciate it.
Excellent video for diagnosing, repairing and replacing. Good job!!
Thank you
You are the man brother, greetings from Australia
great comment thanks, and greetings to The Beautiful Australia, thanks for the time on the channel.
Thank you for this video I was searching for a video on how to replace my fuel injectors. I have a 03 accord 2.4 with 198k miles bought at 46k and never replaced anything except breaks and oil. I recently noticed my rpm gage would bounce at stop light's so after research I decided to do a few things that I have been putting off. I drained 3 quarts exactly of tranny fluid, fuel pump, spark plugs, coal packs, vtc solenoid due to a leak vtech due to leak, serpentine belt, 02 sensors up & down as well as 🐈. My cars mileage recently dropped from 410 miles a tank to 360 I've always had an obd connected to my android screen so I've always known how many miles I was getting and if my rpms were off. I recently paid $145 to clean my injectors and the 1st week on a full tank I got 424 miles on a tank I was amazed till the following week and it was gone so this is why I truly believe it's my injectors. I purchased some for $65 and will be installing them today.
great job, and thanks for visiting this channel.
@JM Auto Repair so I installed my injectors reset my gauge and will update at a quarter of a tank which will be sometime Saturday. I did notice that cylinder 1 and 2 injectors were so dirty around the o rings that at one point I thought it was going to break trying to get them out. Almost all my clips had snapped because they were so brittle but I used a tie to make sure they were in all the way. I had trouble trying to put the new injectors in so I sprayed a little break cleaner on the o rings and they went right in.

Great video I fixed the problem by watching your video.
Glad it helped thanks.
excellent diagnosis .. !
thanks you for your beautiful comment.
Very nice job Thank you 🙏
thank you
Thank you my problem is mine is misfire from cylinder 4 and I cleaned my mass airflow sensor new spark plugs and coil packs I’ll try the injector to see if that work or not
sure try the injector see if that is the problem. thanks for coming to my channel.
Gracias hermano por este excelente video, 🙏
gracias por su comentario y vendiciones a todos
Hi, I have replaced the coils and injectors. It ran good for two minutes and then started to misfire again. I have no way to check compression. Thank you!
HOLA , I changed fireplugs, ignition coils and fuel injector, but problem is still there. Check engine is flashing and it does't go over 20 mph. Please help
hi and thanks for your comment, have you done a compression test? if compression comes out good, then most likely it is going to be electrical problem in the wires also is one or more cylinders misfiring?.
@@JM-AUTO Thanks for replying. 1) How to test compression? do you have a video about it ?
2) The read at O'reilly said it's misfiring on 1 cylinder.
@@rebdawi2002what was the outcome?
Great video thanks !!!
thanks for the video, before purchasing any parts, i will share my situation.car was running fine with no misfire but recently the past weeks, i went to work and my brake lights were stuck on (the plastic plunger that activates the lights was broken above the brake pedal) i had just parked to go into work (king taco) and didnt have time to figure out how to fix it. when i got back the car battery was completely dead (car was parked with rear lights on for more than 7 hours) I had jumper cables and was able to jump it but i have a feeling it may have done something to some cable or electrical something somewhere. when i jumped it starts but i get p0301 and the check engine flashes sometimes and then goes solid. I had to use the vehicle to go into work another few days and i notice after a few minutes it would run somewhat better. All be it to be honest the entirety of me having the car ( 6 years maybe about 35k miles (car is around 189k [2001 honda accord coupe lx 2.3l] i never changed the ignition coils or spark plugs, a few months ago i had put some fuel injector cleaner in. would the issue more likely be linked to distributor? online im looking at all these parts. ignition coil. i see something listed as ignition coil but it is more of a small squarish thing unlike the longish ignition coils. it is probably best bet anyways to check the spark plugs. wires hav enot been changed on the car so i would not be suprised that it might have been singed by too much power, at first when i connected the jumper cables no power was being cycled, but i move the alligator clip on the jumper cable. again and it made some sparks, i got the car started after that but since it runs poorly. on ebay for around 100 bucks i see a tune up kit that has a lot of parts relating to igniton, new spark plugs distributor rotor, spark plug wires, but it doesnt have that one square looking ignition coil pack (not ignition coils themselves) better bet to go overkill and get new parts because i have not done before and also i dont have much time to troubleshoot now, just wondering if the coil pack would be a better than the coil itself, but if its only cylinder 1 misfire....
at any time when the check engine light flashes dont drive the vehicle like that because that causes damage to the engine. you should exchange the spark plugs a coils to difeferent spots and see if the mis moves.
@@JM-AUTO the check engine light was not flashing as I was driving, it flashed for about 15 seconds and then went solid. Car had been sitting for a week now till I order parts
@@JM-AUTO I also wonder if my fuel injector is not working properly. They have never been replaced to my knowledge, after the surge of power from the Jumpstart I would assume some electrical issue. There are also other issues on the car. The car was running fine (no misfire before the battery died and I had jumped it) after that battery and the surge from the jump I'm leaning towards which part it could have affected. Could a spark plug go bad all of a sudden like that? Ignition coil more likely or it could also be worn old injector that finally crapped out from electrical shock. The car does need a tune up, it wouldn't hurt to put those parts on, but I'm hoping it's not an ecu or battery issue. The cars had an egr issue for a while i need to clean the plenum. Recently it's been overheating like it seems the cooling fans aren't cooling well enough. My Honda needs some TLC! Battery was replaced brand new months ago. Alternator was changed but i notice the battery box is rusted with battery corrosion and my dash lights would flash super fast for a few seconds but I would not notice any driving issues
Can you suggested a good source for injectors and what was the scan tool again? Live data is always best
Good job. subbed
Bosch, quality and time-tested performance, Whether you're driving a compact sedan or a turbocharged sports car, Bosch fuel injectors are synonymous with durability and efficiency, here I used standard which is also fine for me. Autel MaxiDAS DS708.
On my Honda Accord 2014, the engine position is upside down with the headers in the back and the catalytic converter in the front. Weird huh?
We having the same prob po301 code helpful video
thank you.
Great video, Are you in CA??
hi thanks for the interest, unfortunately im not in CA.
What is that black small cap on the fuel rail injector? Left side on top of the wires. What its call? Mine cracked and broken. Is it necessary?
it is necessary but if it does not give you problem then you should be ok, that is the fuel pressure regulator.
When I press on gas a little bit noise comes from engine side help?
What kind of oil do I use in the o-ring when I put back rail with new injectors?
you can use almost any oil but I use WD-40 to lubricate the o-ring, thanks for sharing.
Hi, I did all that and still have misfire on two and three. Any ideas? Thank you!
check the wires on each affected cylinder for ignition coils and injectors and also check compression on those cylinders.
I change spark plug injectors and coils still misfiring cilinder 2and 3 what should I do….🙏🏻🙏🏻
you should do a compression test and also check the wires for coils and injectors. hope you find the issue.
What is the name of the OBD 2 Reader you have ? Do you have to pay every year to used it .? If you don't pay will it work still ? How about Updates if you don't updates will it still work ? Does it check Compression for the SparkPlugs ? Does it check Fuel Pressure like Injectors Fuel Pump ,Fuel Pressure Regulators ?
I need one like that .I also have a Misfire issue in my 2003 Buick Park Ave 3.8 Liter .P0302 Cylinder Misfires .I already change the Coil All Coil Pack is new .I also change the Spark Plugs they are all new and Also I have a new wires all new But then it Misfire in Cylinder 2 .I believe it is the same with your car .
this one is an old scanner, Autel maxidas ds708, it checks compression for some vehicles n it does every thing else too but you have to check what manufactures you work the most because no matter how good a scanner is it still will not perform some tasks on some specific years and models, I have about 6 scanners and still not enough because every vehicle is different n some scanners will do better than others, every thing will depend on what car you are working on, and yes I pay every time I update it, but it works with no problem if I dont update it. it does immobilizer n programm keys on so many vehicles.I love this scanner.
@@JM-AUTOMy Last question is Do you have to pay every Year or monthly to keep all the Features on to this OBD device ?
Now if you don't pay every yearly or monthly can you still used it to scan for everything ?
@@jamesmichael8549 yes you can use it with out updating it n keep any updates from the last update you did, I updated it about a year and a half ago n I have no problem, now if you buy the new one then you have to update it every single month other wise you cant not use it.
Did you find out which tool he uses?
@@rockyjr1522 He uses Autel Maxi scan tool . I used Top Don ArtDiag 600 S pretty much do the same it also have a live data . Hyper Tough HT 500 is also good .
Did you ever make a video on how to clean the injectors?
no I have not, I 've been trying but I have never had the time but I 'll see if I can make one in about 2 weeks. thanks very appreciated.
hi can u pls send me a link for the new injector u purchased pls i have the same car
part num: BZ182BV, brand: standard motor products
Changed plug coil and injector engine the same misfiring on number 1
check electrical connectors(wires) on injector n ignition coil for that specific cilinder n finally compression test on the cylinder.
Hey where is your shop ? I have the same problem
hi, I'M in The State of NY, WHRE YOU?
Gracias muestro
gracias a usted por visitar este su canal.
Hello there, I have the same car and cylinder 1 is misfiring but I've replaced spark plugs, switched ignition coils, switched fuel injectors, tested the compression.
All good but I still have missfire in cylinder 1.
And yeah I've changed vtc actuator too.
Please help
thanks for commenting on my channel, after every thing you have done next you should check all signals to the ignition coil to see if is receiving ground, power and signal from pcm and do the same with the injectors and most likely the problem is going to be in the wires or uptate pcm, if you have more question dont hecitate, God bless you and your family.
@@JM-AUTO Thanks a lot, I'll do what you told me and I'll get back to you.
@@JM-AUTO i
Any update my Honda is doing the same I’m going crazy
check the electrical or wires of the ignition coil and injector, since you have the the basic.
What OBD are you using?
autel maxidas 708
Thank You
@@rockyjr1522 thanks
Hey where are you locate?????
Hi, I'm in NY, thanks for the interest.
Bra
I am confused how you fix you just you switch that all?or you did something in scanner??
welcome to my channel, if you have a scanner with live data capibilitiy then you can see live data and see exactly what is happening, so I switch ignition coil pack, spark plugs and injector as you can see it in the video, in my case the injector was clogged and I did not want to clean it but I replaced it and you dont do any thing in the scanner except watch live data. any question dont hacitate to ask. thanks for coming to my channel.
