Generally speaking if there's a miss on both #4 and #5 it would require that both faults be fixed to eliminate the problems. The fuel filter could also be at fault, but consider… If you fixed #5, as you stated, but #4 is still missing maybe there's an issue with it also. If the filter hasn't been changed in a long time, do it. They're not expensive and easy to replace.
