I have a 2009 1.8 sedan, very vwry clean car with 240k miles. Ive been dealing with misfires for the past 10 months, im a Tech and just couldnt figure it out!! Ive gone through 10 coil packs, thats one per month... A set of NGK Iridium plugs, Replaced Engine & Trans Main ground straps, and last weekend i replaced the throttle body also. If it ever fixed it was always very temporary, within a cpl days it slowly walked back into misfiring and became more and more stronger of one. Well ive really been thinking O.T. lately about its symtoms being im the owner and drive ot daily which ive hated every minute of lol, something told me to pull the fuel pump sending unit out so i did earlier today!! Low and behold the fuel strainer was pure BLACK. I cannot get ahold of a new complete sending unit quickly so had to reinstall the filthy part back into the tank. But being i disrupted everything in there and drained out the pumps cup i must have released a clog temporarily and right now my car is literally running and driving like a brand new civic, NO JOKE! Idling perfectly, Shifting very nicely, idle is stable and not bouncing all over the place and its just all around smooth right now. For having 240k miles youd be amazed how good this car runs and drives. Its a super clean car also for being a 2009. Was one owner before me and was always garage kept so theres NO RUST underneath, not even corrosion. Now i have it and keep it Garage kept also. Now that this car will be running perfectly i can finally set forth my plans for giving it a full make over! Come spring time this car will be show quality esp with the plans i have for it. Im a Mechanic, but also a Body Tech who works at a body shop so i have the means and resources to do alot! This might just end up the only covic sedan in the world with a Targa Top....Only civic in the world like that in general. Ive been discussing the idea with a coworker discussing planning & fabrication of it. Will have to fabricate a roll bar set up for roof strength. But im really looking fwd to giving this beauty a full on Make-Over, suspension, wheels & tires, fabricate wide body fenders, Ding removal, paint reconditioning, Mugen Ground Effects kit, White LED light rings behind the wheels, Rear Disc Brake conversion, Interior overhaul, and lastly Stereo Over haul and customization! She gonna be a beauty!!
@@johndavidobusan4947 not sure if I had figured the problem out yet with the misfiring when I wrote that comment, but what it came down to and what kept burning out coil packs was for a year I had Intoxalock Ignition interlock in my car from having a DUI. Turned out that the Device was keeping the Coil Packs energized full-time and not momentarily like they should work. Thank God that Device is gone now because my car runs great. Those interlocks really ruin ppls electrical systems, meanwhile the company swears up and down they don't. Screw them.. When it came time I removed it myself like I wasn't supposed to and sent it back. Also refused to pay the remaining $250. Cost me alot more in parts all year.
I've got the same issue it kinda seems like a fueling. I'm assuming there is some sort of pressure regulator between the high and low pressure ends of fueling if anyone knows if that could be the issue I'd like to replace it myself if possible.
I have a 0498 and its misfire is weird. Same exact shake, not sure if its coils, plugs or what but im not sure if that code even affects engine firing.
@@cacs9823 mine was the ignition coils. The coil pack I had purchased didn't perform how they needed to so they got replaced for higher quality parts and it runs smooth.
Often times that's up to the customer and not him. He can recommend it but the customer may not want to spend money for new coils or simply just can't afford it.
Man you mechanics over use the hell out of those impact guns. These civics have literal torque specs for engine related bolts. You threw that spark plug cylinder in there and just impacted the living hell out of it into the engine block.. lol this is exactly why i do all my own car work. I cant even remember the last time i brought my car to the mechanic. For this very reason here. Lot of you mechanics just are in a rush and have this attitude of like “its not my car so why should i care” .. not good

I have a 2006 FD1 and exactly similar situation. I did everything you mentioned above before replacing fuel strainer and that did the job. Thanks
I had P0301 . Mistfire in cylinder 1 and my issue was not the coil seeing as they were brand new . The issue ended up being a bad fuel injector.
Same thing with me
Fixed my Honda thanks to you!!!!!
Thank you for video. Do you recall how many miles were on the car?
Unfortunately I don't but thanks for the support!
Thnx a lot loved the vid
do you count cylinders (coils) 1-4 from left to right?????
Yup
Thanks for your video...
Before I changed my coils and spark it said one code after changing all plugs and coils 3 codes popped up saying all cylinders misfire
Cylinder 4 does nothing on my car i replaced coil an spark plus & checked compression its all good . Help ?!
Check fuel system
I did that I switch coils and put new spark plugs
Still shake and misfire didn’t go away
What misfire codes are you getting?

That cng sounds so beefy lmao mine purrs compared to that xD
even if 1 fail, you should be changing all the 4 Ignition coils..
Often times that's up to the customer and not him. He can recommend it but the customer may not want to spend money for new coils or simply just can't afford it.
I change the plugs and coils on my 2003 civic but still adjacent a misfire in the 2 & 4 cylinder. Any idea?
Could be your injectors
3 & 4 aren’t firing on mine please help ?
