The idle adjust screw is located on the intake mani. It's usually located near the back of the intake plenum. I'm not familiar with S14 KAs, so I'm not certain if the access position is the same as on S13s

Has it always idled that high? the idle adjustment screw cant adjust if you air reg is stuck open or temp sensor is broken etc.

first thing would be to clean throttle plate area.

look up idle in tutorial link in my signature. do search of high idle in forums

I'm not sure but the idle adjustment screw is not going to help you out. You need to find out where the extra air is coming from ie stuck throttle plate, open air regulator, hole in vacuum tubes, faulity iacv, throttle cable snagged, etc.. You always clean your throttle first in case like this.
