Engine stutter

[Youri Lamie]

Hey guys first time posting.

Recently bought a Mazda 6 MPS in the Netherlands with 180000 km with a new transmission (10000 ~ km).

I love the car but the engine stutters and misfires if I accelerate quickly. About 3000-3600 rpm it's starts stuttering. Also the check engine light is on

Obd2 scanner said it was a p0300

I reset it did an oil change and spark plugs change
After that 2 times I got the p0300 and 2 times I got the p0304 code.

The p0300 showed 24 misfires on the 4th cilinder and on cilinder 1,2 and 3 had about 2~3 misfires.

So I think the coil pack for the 4th cilinder is broken. I checked the coil packs with an multimeter but they all had the same resistance.

So i switched the coil pack with cilinder 1 and cilinder 4. Now the misfires are on cilinder 1. Is it really the coil pack or could it be something else?

PS: the files below are the check engine light reading snapshots and the last one is the misfire counter when I changed the coil packs

So, you had misfires that you traced to cylinder 4. Swapped the suspect coil pack to cylinder 1 and the symptom follows the coil pack?

Sounds like you already know what your issue is.

No it's probably your driver's seat being in the wrong position. /S
As others have said, yes it's your coil pack replace it and go from there.
