Hope its ok and its nothing worse . Lots of cars misfire, they should still be ok.

But checking is the best idea!

well, previously I think piston number 3 was flooded with oil because of the valve cover gasket. Oil might be causing the spark plug to misfire but I need to check… Kinda scared what the outcome will be. ordered new spark plug wires just in case.
