Absolutely sure its the injector? Or is it just a cyl 3 misfire? If you narrowed it down to an injector, have you checked the harness with a noid light? Also, try testing the injector your self. You can also try swapping the #3 injector with the #4 injector. Im sure you have a code for a cyl 3 misfire, clear it. Swap the injectors. If your misfire code comes up #4 then its that injector. Replace it.

Usually the injectors get their signal from the coilpacks. Have you checked compression in the # 3 cyl?
