Over the weekend, I connected a DTC AutoScan into my OBDII and one of the codes came up as [Cylinder 4 Misfire]. Thus, I am a home mechanic; but I need to confirm with experts. I am assuming that I need to change the sparkplug wire and/or sparkplug. There's some traces of motor oil I found on the sparkplug, when I replaced it about a month ago. I believe there's an internal leak in the engine chamber for that particular cylinder. Thank you in advance for any feedbacks or suggestions.
Remove the valve covers and check the spark plug seals .. maybe theyre old and brittle and need replacement.. maybe arent sealing well and allowing oil down to the plug
not hard at all to change urseals...definitely can do urself...u need a flat tip screwdriver to pop em out, thats it
i was having the same issue only with my #4 cylinder, so i replaced all plugs and wires, still misfiring. i can smell gas on the spark plug #4 also. ive read to check the cap? which cap? and i have also been told that my coil pack may need to be cleaned? the ignition coil pack? or is there some other coil pack? please help!

Car not starting or turning over indicates towards multiple possibilities.
It can be issue with battery or weak battery. But if battery checks out ok, then
it can be starter issue or faulty alternator or problem with low fuel pressure
or no spark at spark plugs due to dirty spark plugs or faulty
ignition coil or injectors getting cracked or dirty and needs to be cleaned.
To confirm the problem, the basic troubleshooting is required.
