sorry for !!!1 but i need to upgrade mine

but im confused i have read so many injector threads im not sure what is what and for what year jeep. is there a thread that has all the complied info on what actually works?

it seems like there are so many different injectors that work and every one has a different preference.

i have a 99 if someone could point me in the right direction please
 
You have gray top injectors that are rated at 23.2#@49psi(96-99 had these). The most common rating is 43.5psi(3 bar), but many older Ford injectors(common ones are the 19# yellows and 24# blues) are rated at 39psi. You should look for a replacement injector rated 21.5-22#@43.5psi or 20.5-21#@39psi. Look for injectors that have 4 pintles(finer spray=better atomization). My 96 came w/ the gray tops and are ev1 connectors; I assume the 99 still had the ev1 connectors if they're using the same injector. I believe the 00+ models have ev6 connectors. There are adapters to use ev6 injectors w/ ev1 harnesses and vice versa, but I'd go with an ev1 injector and not deal with an adapter or solder in ev6 connectors if I did use ev6 injectors(wouldn't want to introduce another potential bad connection).
 
awesome
so i need ford high resistance EV6 injector with a Bosch style housing, rated at 21.5-22#@43.5psi or 20.5-21#@39psi with 4 holes
