Misfire help please

I have a misfire on cylinder 5 but I just changed the spark plug . What else could it be? Also the cylinder bank 2 code is gone this was when I was switched the spark plug. Cleared the codes but the misfire on cylinder 5 is still stored and current . What should I check?

Logically it could be a coil pack. Try moving #5 coil pack to another cylinder and see if the misfire follows it.

Got it , I’ll attempt it when I get home from work. Just in case it’s not what else should I keep a lookout for?
I was driving normally without no codes and healthy engine .

I have had two coil packs fail on my 2013 C250. The odds are good that this is your issue. OEM coil packs are readily available.
