Injector ?s

My ass. Look at it.
Okay,...so Ive been replacing my injectors lately and have been wondering why they are all going bad. They are stock 32#ers, stock FPR, stock FP, basically my truck is stock, besides some of the intercooler mods listed in my sig.
All of my injectors "look" fine meaning the "caps" are all intact. They are just retarded internally, they stick and go lean, causing an inbalance and "shudder"-not tach. flutter though.
I know the stock injectors are pretty sensitive, and nead to be cleaned a lot, but I cleaned them all last week, and they ran fine untill a couple nights ago when they started to make the characteristic "miss" that they make on my truck.
My upper IC leaks a little, Internally, which means that it may spray dexcool onto my injectors-would this cause them too foul? Ive also noticed that they usually go bad after I get into "more than usual" boost.
I will be replacing the last three tonight, so maybe this may end the madness, just though Id ask for ya'lls ideas on this.

TIA

Have you had them professionally cleaned?

there is a TSB on that, basically that one method (common one, FYI) ruins the injector.

Man, I wish I could have them cleaned professionally, not a single place around here that can do that :x Ive just been using some aerosol BG cleaner that seems to work well, but I cant have them matched and or flow tested around here.

crap in lines after the filter? i.e rust particles breaking off? i dunno

Well, I dont think so, unless the higher volume of gas allowed at boost would knock anything loose?

The new injectors I installed last week are Ok AFAIK, they drop to exactly the same pressure when pulse tested. Maybe the other three are are getting ruined trying to keep up with them, but when I cleaned them all last time, they ALL dropped to the same pressure. :-?
