had a code po302 cylinder 2 misfire detected so changed coil pack plugs plug wires and ignition module still po302 code and now po202 injector circuit malfuntion do i need to change the injector if so how do you change it and how much do they cost

 

It could be the injector or the wiring to the injector. I would go to the junk yard and get an injector and the wiring.
