basically all you have to do is pull the vacume hoses, after you do that you unbolt the intake manifold and the fuel pressure reg,and mabey 1 or 2 things more on the auto, you then relive the fuel pressure using the fuel pressure relief bolt, then you just unplug the injectors and pull out the fuel rail, drop in the new ones wtih new seals and away you go. its pretty easy, just dont lose your bolts and take your time. and dont drop the injectors, that kinda sux.....

What did you do to keep from getting the vacuum hoses mixed up?
How much time would you say is involved in a project like this?
Is it really that easy to do? Maybe you just make it sound easy. I dunno.
Thanks

First do a compression check. If it in spec, great. If not then perform a cylinder leak down test to find where the compression is leaking from. That could be your idle problem.
Once you verify the compression is good, get a Motor Vac carbon depletion service done. It will clean the injectors, intake valves, and combustion chamber all right on the truck.
Rarely do the injectors need to be replaced. Cleaning them ususally solves most problems with them, and much cheaper. You are likely going to pay about $150 for each injector at the dealer.
