I have a 1990 240 and I need to adjust the idle. Can someone tell me the location of the IACV.

ok i also have a 90 240sx. I bought a chilton manual and it tells me u can't adjust the idle on 1990 model or higher. plus i cant find it im thinkin the intake manifold is the E.C.C.S but i guess im wrong? can someone help

intake is the eccs thing. on the back of it, look for somthing with a flathead screw on it. the screw should be pointing towards the pasanger side of the car, and is kinda recessed. if you still cant find it, i can use paint to show you were it is in a picture.
