My 2015 has about 60k miles, and just recently has a misfire on start, but runs fine after. It's also from a cold start and idles just fine (and drives fine too)

Any ideas what it might be? Made an appointment for new plugs but Mercedes books over 1 month out where I live.
Check the coil packs. I had one that went bad on me and caused the same issue.
