6-22 FUEL SYSTEM AND THROTTLE BODY
FUEL INJECTOR INSTALLATION
• Apply thin coat of the engine oil to new injector dust seals and
O-rings. (6-19)
• Install the injector by pushing it straight to the throttle body.
Never turn the injector while pushing it. (6-19)
FAST IDLE
The fast idle system is automatic type.
When the fast idle cam is turned by the secondary throttle valve
actuator, the cam pushes the lever on the throttle valve shaft
causing the throttle valve to open and raise the engine speed.
When the engine has warmed up, depending on the water tem-
perature, ambient temperature and lapsed time, the fast idle is
cancelled allowing the engine to resume idle speed.
FAST IDLE ADJUSTMENT
• Lift and support the fuel tank. (6-3)
• Start up the engine and run it in idling condition for warming
up.
• Set the idle rpm to 1 100 rpm by the throttle stop screw 1.
• Check and adjust the TP sensor. (5-19)
• Measure the TP sensor output voltage at the coupler
(between + Bl/B wire and - B/Br wire).
