Search for my questions and you will find all you need to do it. If you dont have a Factory service manual get one from eBay or helms they are a big help. Yeah she will be down for a few days if you send them to be cleaned at Cruzin but from what I have read no one has been dissapointed.
Your problem may not be the injectors anyway it might be the Idle Air Control you need to get a fuel pressure gauge that hooks up to the fuel rail and check for pressure once again search the forums. It could also be the fuel line check valve. After you have the gauge on turn on your key is should jump up and then turn it off if the check valve is bad it will got down pretty fast if it is a injector not so fast should hold pressure for a little while. I am new to 'Vettes myself and have learned a lot here the guys are really good.

as for the fuel injectors, i dont feel QUITE as overwhelmed,
relieve fuel system pressure,
remove intake plenum and runners,
remove fuel rail assembly,
rotate injector retaining clip,
remove injector by pulling,
remove and discard retaining clip and o ring seals....
i still havent found the "relieve fuel system pressure" section of the book
, not sure what intake plenum is exactly, and have no idea of what runners are, have a picture of the fuel rail, so i think i can locate that. I assume you need to get new retaining clips and o ring seals from somewhere?
thats about the level of understanding im at so far.

Most gauges have a button on the side of them that will relieve pressure to a hose on the side put it to a can and remove gas cap as pressure builds up in the tank. I got mine at Advance for around $35.

It'd be better to have the stockers cleaned, or replace all 8 with new injectors.
