All codes are gone except still has PO301 cylinder 1 misfire. It has always just been Cylinder 1, never random or any other cylinders. What can it be?

I've been having 1,3,5 cylinder misfires. I removed the 3 cylinder plug, checked it and reinstalled it. Cleared codes and went for a drive. Number 3 cylinder misfire went away.
