Kia forte Misfire How to find and fix your misfire 

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

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

Thanks for posting this video! You just saved us lots of $$$ 👍 Turned out #3 Coil Pack was no Bueno!

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

Thank you. Fixed my car

You helped me so much to we’re I feel confident enough to change my own Thankyou !😊

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.

Great info!!! Thank You!!!

Nice e enjoyable video!!!! Have U found other issues related to Kia? I've read they tend to have fatal engine issues.

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!!!!

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...

Great video

Thanks!!!

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!

Great video !!! Recommended clean up engine bay!!!!

Do you know if you have to use kia genuine parts? My husband replaced his 4th one and the code won't clear.

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

Awesome video, is there a link where i can get the scanner and the coil?

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.

Nice video and thanks but the new coil have other design ? Or other number and so thx

If your 10mm coil pack bolt snaps in half, any suggestions?

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!! 😫

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?

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.

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

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

Thanks bro I literally have the same ride and it says cylinder 2 misfire

Good day bro I have Kia cerato 2013 cylinder 1 misfire so please bro can you help me out

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

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

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

Can you post link for scaner tool? thanks

If we changed the coils and spark plug what would be the next possible issue?

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?

you can even say it's "firing on all cylinders" great way to end a video! hahaha

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?

My car has 120k and l remplace the spark plugs and l want remplace all 4 ignition coil,you think it's good idea?

What is changing spark plugs and coil pack don’t work

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???

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?

What the actual length of those spark plugs?

Норм машина.

I got that issue. With mine rn

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.

I just replaced the exact same thing on my 15 Kia soul...and it's still running the same..what should I check now

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

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

😮 i Wouldn't use an impact to tighten that bolt .

Just paid for this repair to realize I coulda did it myself

Plugs don’t cost too much to just replace them.

My code just went away after this, no code follow ....

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.

Could you please stop talking so loud.

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

What size socket do I use for the spark plugs?.
