Icon4 Misfire that wont go away.

I am getting a PO300, PO302, and PO305 codes. That would be a "Random Misfire", "Misfire Cylinder 2", and "Misfire Cylinder 5".

It is a '97 Ranger, V6 3.0L 2x4

Since the readings, I have changed the spark plugs, wires, coil, and fuel injectors. I have finally come to a place that I have no idea what to do and I am thinking about just taking it to a mechanic. I really don't want to because I take pride in working on the truck myself.

Any thoughts would be more than useful. Thank you in advance!!!
