Oem coils?
When was the last time you changed spark plugs?

All coils replaced?
What spark plugs?
I would recommend only utilizing OEM coils, even if tuned.

Swap the coil 4 and coil 3 (or any other) and see if the misfires follows. If it follows you got issue with the new coil. If it stays - it’s something else.

No just the 4th coil was acting up, and the spark plugs are auto light XP iridium, so do you think I should buy a new Hyundai coil? Will it go out again?
Issue is crap plugs and crap coils. Replace with new oem coils part number ending in 2B110 and if you're remaining on the oem tune then get new oem plugs from the 19+ VT and gap to .028". If tuning the car go with HKS M45XL plugs and gap to .024". If you need a good price on the plugs and coils let me know.

No worries I just ordered a new coil ending in the part number that you gave to me I’ll keep you updated when it gets here and if it fixed my issue
A coil will not be the solution here based on how the coils and the ecu operates. Also if you order a coil it will cost like $70 vs $200/4 coils. Get better plugs as well. Heat range 8 only for the oem tune and gap all to .028".

I do!
If you did everything I suggested then the issue will most likely be tune or fueling related. However I was born at night but not last night and know that you did not do that.
Hard to help when you do not follow suggestions to fix properly and you give so little details to start with on the car and the issue at hand.
Trying to take the cheap way out will usually cost you more in the end.....

I literally just swapped out the parts for oem quality how is that taking the cheap way out I’m confused? Also I’m not here to argue I just need some help and suggestions
I'm not arguing either I'm trying to help.
In reference to post #8 did you do what I told you to do so far or not? Your posts and my educated guess says no.
If the answer is no then this is why you're trying to be cheap to properly fix the issue.

okay mr educated guess man, since you just know the answer to everything, can you tell me why it’s still misfiring even after I did what you said in post #8 I changed the spark plugs to oem and the ignition coils to oem, oh and by the way it gapped to 28. it’s a stock 1.6 tune. it’s turbocharged. it’s a manual, I’m the second owner but it doesn’t look like they did any mods to it. Does that help.
