THROTTLE BODY
A (factory adjusted) set screw is used to mechani­
cally limit the position of the throttle body throttle
plate. Never attempt to adjust the engine idle
speed using this screw. All idle speed functions are
controlled by the powertrain control module (PCM).
The throttle body is mounted on the top of the in­
take manifold on 3.9L/5.2L/5.9L engines (Fig. 30). On
the 8.0L V-10 engine, a two-barrel side-mounted type
throttle body is mounted to the upper half of the in­
take manifold (Fig. 31).
