You can remove all six injectors at once, still attached to the fuel rail. Just remove 4 bolts that hold the fuel rail to the intake manifold, disconnect the fuel feed and return lines and AFPR, then simply lift up on fuel rail. You may have to work at it slightly, but mine pretty much lifted right out after 10 years. Each injector is held to the fuel rail by a clip which is easily removed. I would also say it is necessary to remove the upper intake before removing the fuel rail, but may be possible without doing so. IMO it's MUCH easier to do if you yank the upper intake.
