Remove idle-speed control valve (1) to facilitate access to throttle
assembly 2.
Release nuts, remove idle-speed control valve (1) together with
holder from assembly and place to one side.
Gap between stop screw (1) and actuating lever (2) must be
less than 0.05 mm.
To check gap, use a feeler gauge with a thickness of 0.05 mm.
Checking gap:

Pull pull rod of throttle actuator in opening direction of
throttles.
-
Slide feeler gauge (3) between stop screw (1) and
actuating lever (2).

screw (1) and actuating lever (2) and will not fall out.
Perform check on each throttle assembly.

A readjustment must be made if the gap is larger than 0.05 mm
at one or more throttle assemblies.
