as for cleaning injectors by taking them out that will do nothing at all. why don't you ohm out your injectors first?

second nissans are prone to having the o rings deteriated (sp?) with fuel cleaners like the ones from auto parts stores. we used 3m injector cleaner at the nissan dealer i worked at and it was recommended by nissan. it was fed thru the fuel feed line.

and for removing injectors you do not need to remove half of the stuff you listed above.

release fuel pressure by taking out the fuel pump fuse or relay crank engine over.

disconnect fuel injecoter harness

becareful when unscrewing phillips head screws frm injectors you may want to use a impact driver to make sure you dont strip the screws. or just hammer the screw driver in and turn

remove cap and pry up on injector lightly and twist at the same time. viola injector removed!

now when you put back the new injector connect everything back up remove the spark plug for the cylinder you removed crank engine over to ensure you wont hydrolock the engine.

majority of those steps listed are not needed
