How do you adjust?

Specifically,where`s the adjustment screw/gubbins/dupher/whatnot/gizmo/thingy/doo-dah?

If it's the normal setup then it's the air bleed screw in the side of the throttle housing.
Engine off disconnect the water temperature sensor. Start the car and rev to 3000rpm to set limp home mode which parks the idle compensator.
Adjust the idle to approx 900rpm.
Switch off, reconnect the temp sensor then start.
Idle should then be lower than 900rpm but will be smooth when the throttle is released from open.
