ae86 not running right, injector?

[Comrade_charlie]

I checked timing its fine. then I unplugged each fuel injector to make sure they were working and when I unplugged number 2 it didn't make a difference in how it ran, It idles at 1200 or 1300 and the motor shakes back and forth, every other injector that I unplugged clearly made a difference but number 2 might be bad, or could it be a spark plug... Ill go pull the spark plug out. Ill pull the cap of the dist. too.

The ae86 uses a o-ring type injector right? I hate barb type took me forever to replace the injectors on my 300zx, they are barb type.

what injectors can I use, I heard 7mge injectors are identical. I think 295cc but thats just what I read on another forum.
