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!!!

 

I just got done with this issue on #5, ended up replacing the fuel injector.

 

Plugs, wires, coilpack, low compression?

 

James....do you know how to replace the fuel injectors? is that a do it yourself?
