83 Turbo idle adjustment screw location?

Like the title says... Where is the idle screw adjustment on the Turbo motors. My haynes manual has it in one spot but it is definitely not there on my car any help would be sweet.

The idle screw pictured in the Haynes manual is for the NON-TURBO. The 280zx turbo idle is controlled by the ecu. The only other way to adjust the idle is by adjusting the throttle body stopper screw.

I usually replace that screw with a slightly longer one that has a hex head and found a jam nut that was a bit thicker.

Most of the time, I just hold it all the way open and twist the tang that meets the stop screw with a small pair of channel locks since most of the screws are siezed.
