This video was so helpful, thank you so much! I replaced my spark plugs last weekend and this video helped a lot. I'm all for paying people for their labor, but the money I saved doing this myself will go a very long way
You just saved me a ton of money was having this issue took my car to the Stealership I mean Dealership They replaced spark plugs to no avail then charged labor. Still misfiring on 2 and 4 told me they would need the car for a few days and open a tech case with Kia for a bunch of techs to stand around and tell the tech working on my car to replace the coil pack that I had a friend do for me after ordering these Kia parts from Kia. Bought him dinner as a thank you
Thanks for posting this video! You just saved us lots of $$$ 👍 Turned out #3 Coil Pack was no Bueno!
From a mechanic to a shade tree mechanic , DO NOT impact tools on things like that !!!
Furthermore if you are going to use impact tools at least start the bolt by hand so you don’t have to deal with stripping bolts due to the impact tool
great video, I recently had a misfire on my Kia forte 2019 model at 41k miles (just ridiculous) not sure exactly why, but it happened... anyways this made my day because I was going to take this to Kia for warranty.... but instead doing that and waiting a century while they try to sell you on more crap just decided to spend little money to fix it. Just crazy how soon it happened with a car I barely drive. my SUV drives perfect... but this Forte has been some trouble...
Actually mine is a 2022 and I think is having the same issue, just 1 year and when going to high speeds it vibrates
Mine misfired at around 55,000 miles. I've noticed that the car drives rough for such a new car with low mileage. Very interesting.
I have a 2019 Kia Forte.. one day I decided to change the spark plugs cause they needed to be changed. My Kia has 130,000 miles and a month after changing the spark plugs I started to have a misfire so I changed all four coils. After changing the four coils the check engine light is still on and I'm still having misfires, rough idling, and sluggish acceleration. I just wish it wouldnt be so damn aggravating. Now a few days ago the A/C stopped blowing air even when i turn on the heat.. people told mw blower motor fuse is probably blown but i guess thats my next step.
I've had a 2013 and a 2017 forte both started having engine troubles around 100k well the 2017 one not as bad as the 2013 this time it's just this misfire with the 2017 and a p0014 and p0017 code for sensors I had to replace. Bout to replace the coilpacks n plugs next weekend n see if it fixes my misfire. Oddly though turning on the ac for some reason helps alleviate the stuttering while idle and regulates the idle rpm so it's not dropping down to 500 and the car cutting out. Long as the ac is on the car will keep running and idle around the normal 1k rpm. Cars at 103k miles. All I know is this happened at the worst time (right before the scam that is emissions testing). So I've been driving this bad boy around with outdated tags lol. So I need to fix this asap cause I damn well am not paying the hefty fine for having outdated tags if i ever actually get pulled over for tags. You mafuckers going to have to take my license before I pay the 1200 this state wants for a registration ticket.
This is precisely what I needed! My 2017 Forte (identical to the one in this vid lol) has a cylinder 2 misfire plus an increasingly rough idle, so hopefully I can isolate the cause using the tips here.
Thanks again!
I have the same exact car and every 2 years, I have to replace a sparkplug. I'm changing it again tomorrow
Thanks for making this video, it’s -12 degrees outside and I’ve got a misfire in cylinder 3. This made it a very short repair. Ahhh warm coffee!!!!
I have a 2017, and about a year after owning it (~20k miles), the service guy at the dealership said there was a recall (I believe it was actually just a service bulletin) for the ignition coils. The documentation said technician should replace either spring or the entire coil. Of course, it said they opted to replace the spring which probably means they did nothing. Is it even practical to replace the spring? Anyway, long story short, around 45k miles I had to replace the first coil. Then maybe another 5k miles later another one did the same thing, so I replaced the remaining 3. I used Delphi coils since kia branded ones seem to suck. No issues since then. Warranty claim was useless as the issue was intermittent and dealership treated me like I was making it all up.
My mom also has a 2017 Kai forte it also had the coils changed because it was popping a check engine light they replace the coil pack and haven’t had a problem since the car has 104k miles and no problems since it gets put 100 miles a day. Overall a good car Kia has a customer that will be coming back
I bought my 17 Forte used 20k just shy of two years ago 36k now and recently had the same issue there is a TSB SA321 Forte model years 17 & 18 2.0 MPI's for production dates 05-16-2016 through 09-07-17.
I started having a cylinder 3 misfire took it in and was informed that the TSB had already been performed for the previous owner but they said they would look at it. I gave them simple repeatable instructions to coax the issue into repeating itself there wasn't a hard code set yet they claimed no issue was found four days later it happened again. I swapped the coils and the next day it moved to the other cylinder I ended up eating the cost because I wasn't gonna lose my car for another day for them to pull the same BS.
The car drives fine but has never idled smoothly I usually run the HVAC fan on 3 all the time to keep the rpm stable around 950 otherwise it stumbles around 640 and occasionally stutters down to 590
You helped me so much to we’re I feel confident enough to change my own Thankyou !😊
You are welcome!
Nice e enjoyable video!!!! Have U found other issues related to Kia? I've read they tend to have fatal engine issues.
Been having this issue just got the misfiring code yesterday. Definitely thought it might be a spark plug issue, but after seeing this I'm going to check to see if it's this same issue.
Do you know if you have to use kia genuine parts? My husband replaced his 4th one and the code won't clear.
I have a 2017 Kia Forte just like the one here, I have the BlueDriver as well, it’s been throwing a cylinder 2 misfire and after getting all new spark plugs recently, it’s still coding cylinder 2 misfire. I’ve swapped the coil packs 1 and 2 to see if the code follows, and it’s still throwing a cylinder 2 misfire code. What else could be the issue? I’ve heard these gdi engines have carbon buildup issues. Help a girl out!! 😫
The next issue that you could have is the cylinder 2 injector isn’t working properly or not firing at all. You can take a long screwdriver and put it on the injector then put your ear up to the screwdriver and listen for a rhythmic click. If you aren’t hearing anything then the fuel injector is bad. That is what I would check next
Question. I had a misfire on cylinder 4. Swapped the coil pack and the spark plugs, separately and together, still got a misfire on cylinder 4. Would my next step be swapping the fuel injectors? Or what else could I do on my own before I go to a shop
You can check compression on cylinder #4 and if it’s good, then it most likely just needs a fuel injector. The last thing after the fuel injector would be wiring to the injector is also a possibility.
Nice video and thanks but the new coil have other design ? Or other number and so thx
It should have the same design as the original
Changed my plug and coil on my 2nd cylinder with a misfire and my 2014 forte still has a pretty rough idle, especially with the ac on. Any tips?
It’s normal for it to idle rougher with ac on, but if it still ides rough without ac, check the other spark plugs or change them they are cheap. Usually do not get an engine code for just spark plug but will get one for bad coil pack. If that doesn’t fix it, could be fuel filter or something else
Great video !!! Recommended clean up engine bay!!!!
Tons of electronics in todays engines. High pressure water jets have a way of getting into electronics/wiring harness connectors and creating problems, later. Use blue shop towels to wipe down.
Wish me luck the new coil I ordered that's coming in a few days fixes my problem, out of the blue my 2016 Forte started having a cylinder 1 misfire but I honestly think the car also has bad wiring since the check engine light will come on, go off, flash, then even go off on its own and scanners claim there's no code after 1 day finally saying cylinder 1 misfire. Spark plug looks fine and isn't cracked. I needed a new oil filler cap, I think some leaked out and got all over the number 1 coil and ruined it...I couldn't find much info online if oil can ruin coils but I cleaned it and its still misfiring so I guess so....really really really wish the code would show up on my scanner though, that's what perplexing me. I pray to god this thing just lives until it's paid off in 2 more years. I've limped it along for awhile with a pretty bad oil burning problem I have down to 0.5q a month instead of 1q a week it was using before by using 5w30 oil, some RESTORE here and there and Liqui Moly Motor Oil Saver. Really been one thing after another with this car, regret getting it from the bottom of my heart
I have changed the coil pack on my car and and im still having the check engine light on, plus car is shaking when idling and at stops i need help
Did you resolve the issue?
@@mjusto2351 no my 2017 kia forte continues to misfire after coils and wired have been changed idk what to do
@@kevspinz4503 my 2016 ex 2.0 had misfire cylinder 3, changed plugs , coil packs and still misfired , finally they discovered was a plugged fuel injector, installed new injector and running good now at 160.000kms
@@kevspinz4503 I'm in the same boat, and every times I've taken it to the dealer they say they don't know what it'll take, so they're trying to get me to replace EVERYTHING: plugs, coils, and if that doesn't work, the entire engine
That is the same thing happening to my Kia 2017
Great info!!! Thank You!!!
Awesome video, is there a link where i can get the scanner and the coil?
Yes there is a link for both in the description!
Thank you. Fixed my car
Great video
I had a diagnostic done on my 2017 Kia Forte lx at autozone and it came back as a misfire due to ignition coil. My car is at 57,000 miles and I’m assuming it’s never had the coils or spark plugs changed. Is it best to try and locate a specific coil that’s malfunctioning or to just go ahead and swap them all out? I don’t have a blue driver so I can’t determine the exact issue
I would recommend just finding the bad coil and replace the one and you can do all the spark plugs while you’re there. The ignition coils can get expensive so just doing the bad one would be best
@@daringmotors awesome, thanks.
Drew I had the same issue. what now? all new coil packs and plugs still runs rough. UGH
@@lloydhuff4957 I don’t know jack about cars but I’ve read it can also be because of the motor mounts wearing down, or a really dirty fuel filter.
Honestly if you can get the coils cheap enough just swap them all and keep the good ones as spares. Usually when one goes bad they all go bad one by one shortly after.
If your 10mm coil pack bolt snaps in half, any suggestions?
I have a kia forte koup 2016 1.6 turbo change spark plugs and coils and the cylinder 2y4 does not work, could you guide me, the lines are fine, it has 14volt when the car is on.
Good day bro I have Kia cerato 2013 cylinder 1 misfire so please bro can you help me out
Do you ever find some forte have a seized spark plug ? Or hard to take off?? On my kia the spark plugs won’t budge
They can be difficult to remove sometimes and the best way is to get a longer ratchet and work really slow to get it to move once it moves if it is still hard to turn move it back and forth loosening then tightening until it comes out.
@@daringmotors worked like a charm man thanks 🙏 keep up the good content man
If we changed the coils and spark plug what would be the next possible issue?
The other issue could be a fuel injector or low compression on the cylinder
I have no codes but i have this same car and occasionally it will drop idle and run rough then check engine light comes on still with no codes then i have to disconnect the battery then reconnect it and engine light goes out and it runs perfectly fine but it happens every day, i dont know if this car in the video had same symptoms but ive come to the conclusion that it had to be the spark plugs before i found this video but know i think it may be the coil packs too.
But to be sure what were the symptoms of this car?
This car had an intermittent misfire. Every once in a while the check engine light would flash. When the light did flash I would pull over and check the codes and that’s when I found the misfire and diagnosed a coil. It is likely it is a coil. You can test and find which coil is bad or can replace them all with the spark plugs
@@daringmotors yeah thats what im going to do i have everything in my cart already and it has to be spark because my car feels sluggish and from my history with bikes tells me its the plugs
So I had a misfire and intake manifold tuning valve bank 1 pop up they said I’m crazy they test drive they get nothing wrong what do I do
Can you post link for scaner tool? thanks
I added the link to the video description but here it is as well
amzn.to/2KQbjw0
you can even say it's "firing on all cylinders" great way to end a video! hahaha
My car has 120k and l remplace the spark plugs and l want remplace all 4 ignition coil,you think it's good idea?
Yea that would be good for it. For the forte it is normally recommended to replace the spark plugs around 100k. The coils are normally okay to not replace but it won’t hurt it.
@@daringmotors thanks you
Thanks bro I literally have the same ride and it says cylinder 2 misfire
Thanks!!!
Dude I'm about to lose my mind over my Elantra GT Sport ( 1.6T Tv2 ) ever since 15k miles it's had an extremely rough idle, power loss between 3k-5k rpms, and has gone into limp mode multiple times. cel intermittently flashes all the time, esp under load or when idling for a while, and back in May it finally stuck on a permanent code. Pulled them - P0001-0004 all 4 cylinders misfiring! Took it to the dealer they cleared the codes and said nothing is wrong. As soon as I left the dealer cel came back on. They then said it was my injectors due to bad fuel ( I only use 93 and this has been constant for a year ) get the car back still misfiring. Took it to another dealer and they won't do anything bc the cel is back to being intermittent, they say they need a permanent code to warrant a replacement. I'm so sick of ts. I told them screw it ill buy the coils and do it myself. $900! Absolutely insane. Idek what to do man. I'm about to lose my mind tho this is absolutely ridiculous.
Dude I’m having the same issue but with my 2015 Kia forte5 sx! Did you find anything out on what the issue was?
@@Infuizongamer yes, finally did and it's bittersweet. Dealer finally looked into the issue after dealing with this almost a year ( they kept sending me away bc the cel was only intermittent ) and they found out that 3 of the cylinders had lost compression due to scoring and checking on the cylinder walls. They're saying it was due to carbon build up which is insane at 15k miles... luckily I have a warranty still so it's been there for about a month and they're replacing the engine. It sucks tho bc they gave me a loaner but I'm having to pay $35 a day to use it, they've had the car about 5 weeks or so and saying another 3+ till its finished... really sucks bc of all the time and money I've wasted when the whole time the engine was essentially blown ( bought this way cpo ) and now they're charging me to use a loaner bc the cpo car they sold me was shot from the beginning 🙄 a couple years ago I saw a Forte5 SX that had this same exact issue too and it seems pretty common with Hyundai GDIs so that's definitely what I'd check, do a compression test
@@_dmfd so in other words your gasket was leaking combustion mix and your cylinder walls were worn down? Am I understanding that correctly?
@@Infuizongamer was this issue ever fixed? I am currently having the same issue with same make and model and it has been a nightmare. Looking for a new vehicle unfortunately
My Kia Forte shuts off while I’m driving but it’ll start back up, I was told it’s the ignition control module, help?
I just replaced the exact same thing on my 15 Kia soul...and it's still running the same..what should I check now
It could be a bad fuel injector or the wiring to the coil could be bad
hi i had a misfired on cylinder 3 and i had to do new spark plugs, then i used my scanner and misfired on cylinder 2,4. i went back and try to check if the spark plug where loose. afeter 10 miles the kia was running great but i turned off and turned back on and engine light was on again, i use the scanner and now i have misfired on cylinder 4. Can you help me please what is going on whit the engine???
Did you replace all the spark plugs? Or just the one?
@@JujiSmurf hi, i replaced all 4, now i'm thinking on fuel injector problem
Mines doing the same thing help
I believe there was a recall recently, I'm not sure for this specific problem or something else.
Hi sir, I've got the same problem on my KIA Forte 2011 but after installing new ig coil, spark plug, new ig coil wire, still there's no spark on cylinder 3, can you help me please?
If there is just a misfire it could be a fuel injector that is bad. If you test with a spark tester and there is no spark then there could be a shot to the ignition coil
@@daringmotors okay sir, thank you for your help
Can you post link for the scanner tool?
What is changing spark plugs and coil pack don’t work
Next would be checking fuel injectors and if they are firing. If they aren’t it could be a bad injectors or a wiring problem. Last thing to check after that is if there is good compression and it is equal across all cylinders
I did exactly as u did and the check engine light is still on...I changed all 4 spark plugs and 1 coil #3 and it's still not running right
If you are still having problems then there could be an issue with the fuel injector or the wiring to the ignition coils.
Can anyone help me. I am having a cylinder 4 miss fire. I've changed the spark plugs and swapped the ignition coils. But I still get the cylinder 4 miss fire can it be the wires or the fuel injector?
If the issue isn’t with the ignition the next thing to check is for the injector and wiring and also do a compression test to make sure there isn’t a base engine issue
@daringmotors what do you mean "isn't with the ignition ". But yeah that was my next step to check the fuel injectors and go down the list to the wires
Sorry by “isn’t with the ignition” I mean the problem is not with the spark plugs and the ignition coils
I had smelled gas and there was car shake and misfire/engine light. Happened twice. I let it sit 5 sec and tried again - it worked. Never happened again. I assume I didn't tighten gas cap correctly or something. KIA Forte 2018
What did u end up doing mine is shaking a lot
@@leonardoe5695 it never happened again. I think I didn't tighten that cap properly
What the actual length of those spark plugs?
I’m not sure the length the best way is to compare the current with the old
Can u have a misfire on a kia without a engine light
If the misfire is small enough sometimes you can have a misfire without the light however most of the time if there is a misfire the light will come on
This what the mechanic told me.. The reason I took it in when I would accelerate the car wouldn't move like the car wanted to stall out it seemed like something got hot on the car and that's when it would start to not run.. The mechanic told me it was Coil 1 misfiring.. Thanks..
I got that issue. With mine rn
Just paid for this repair to realize I coulda did it myself
😮 i Wouldn't use an impact to tighten that bolt .
My code just went away after this, no code follow ....
Норм машина.
Plugs don’t cost too much to just replace them.
The hell they don't 200 dollars for all 4 2010 kia forte. 😒 🥺
Those plugs are pooched, don't be cheap, replace them.
New cars and trucks suck plain and simple not built to last and the parts fail before they even reach a warranty period pretty crazy how people actually like the plastic pos vehicles out now days.
So i was told that a misfire on cylinder 3 is a misfire based on the firing order of cylinder. The firing order is 1 3 4 2 so cylinder three would technically be 4 if you understand that. I just want to double check if thats correct
That’s is not correct at all the misfire is based on the physical cylinder number not firing order
Could you please stop talking so loud.
What size socket do I use for the spark plugs?.
I believe it's 5/8
woowee thats a dirty engine. i had no idea that the cylinder coils were interchangeable! my 1st cylinder is misfiring.... that a good way to test it! i mean it makes sense, but i just had a duhhh moment
