Engine may have coil packs and not wires. Some of them fail and should set code if on input side.
I would first replace the fuel filter.
yes but they still have a spark wire from coil to sparkplug and fuel filter wont cause engine misfire but a bad fuel injector will;
usually if a injector misfires it will make the check engine lite flash continually
