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...
