oh. heres how i would check:

while car is running, remove each plug wire one at a time. if you remove one and it doesnt change the idle, troubleshoot that individual injector wire by checking the continuity from the ecu. just an idea.

the fourth plug furthest from the battery does not change the idle.

did you ground out the injectors in a good spot? there is a ground wire for them, if it's not grounded right it'll act up.
