I just recently replaced all my injectors.
Once you get them out, you'll see the o-rings aren't that difficult.

i have taken them apart. do you mean the large o ring that seals the head from the injector body? (the part that sticks up?) they are easy to unscrew when you have them apart. just hold the body and twist off the head. it may take some huevos to get them. i believe my teacher put the body in a brass jawed vise, but don't do it until i get back to you on that. dont want you to eff up your injectors

I can't tell you for sure if the spring gets weak. It would probably need a million miles on it before it did get weak. It sounds like you need to graph the fuel rate and rpm during a koer test to pinpoint the bad injector. Or call the guy up and tell him to send you a set under warranty and you will send him the old ones back. There should be no miss at that rpm range.

I don't have any way of graphing fuel rate for my truck unless I could do it with my VAG.
