OBDII code P0304

Single mom with dumb kids... Jk
My daughters 2001 Focus SOHC has code P0304 I know that's cylinder 4 misfires. We've done plugs and wires today. Had full tune up last summer. Thinking about needing to do the injectors?? Anyone have this prob or advice??

You might consider switching the #4 injector with any other one and see if the misfire moves.
