Well from what a spokesman from GM told a friend of mine about injector cleaners that you put in your gas tank is that it can cause the in tank fuel pump to fail since its nylon bearings use gas to lubricate them, this might not be true but I would think it would hold true to any car, truck that has an intank fuel pump. As far as cleaning the valves they do this becuase fuel is sprayed in the intake and travels over the valve thats how their cleaned so other then the pump issue I wouldnt see why it wouldnt work. You can also take it to a garage and have them clean your injectors ( you may possibly be able to be the cleaner set up your self but it may be priced high).
