Injectors?? Man they are easy to swap out. The thing that I cant remember how to do is depressurize the fuel system. You dont have to do this, but it makes less mess as far as leakin fuel everywhere. Some guys, put a lil grease around the rubber injector seal too, besides that it is just pull out and replace. You will have to remove the intake to reach the passenger side fuel rail though. Hope this kinda helps!
