Cylinder 3 misfire

OK so this is the second time happening in the past few weeks. Replaced all 4 coils and plugs. I did recently put a hondata basemap on the car without a proper tune. Would this be a reason to cause this problem?

Is this on the Hondata basemap or Hondata factory map? I never saw a resolution to the last thread, but I'm hoping you followed the advice and reloaded a factory map.

Did you have proper battery voltage (meaning you didn't get a voltage warning from Hondata) while reflashing? Where did these new plugs come from?

Have you tried swapping the coil and/or plug from cylinder 3 into another to see if that moves the misfire?
