FUEL SYSTEM
s
GENERAL
• Bending or twisting the control cable will impair smooth operation and could cause the cables to stick or bind, resulting
in
loss
of
vehicle control.
• Work
in
a well ventilated area. Smoking or allowing flames or sparks
in
the work area
or
where gasoline
is
stored can cause a
fire or explosion.
• When disassembling fuel system parts, note the locations of the 0-rings. Replace them with new ones upon reassembly.
• Before disconnecting the fuel feed hose, relieve fuel pressure from the system (page 7-6).
•
Do
not snap the throttle valve from full open to full close after the throttle cable has been removed. It may cause incorrect idle
operation.
• Seal the intake ports with tape or a clean cloth
to
keep dirt and debris from entering the engine after the throttle body has been
removed.
•
Do
not damage the throttle body. It may cause incorrect throttle valve operation.
• Prevent dirt and debris from entering the throttle bore and air passages after the throttle body has been removed. Clean them
using a compressed air
if
necessary.
•
Do
not loosen or tighten the white painted nut and screw of the throttle body. Loosening or tightening them can cause throttle
valve and idle control failure.
• The parts
of
the throttle body not shown
in
this manual should not be disassembled.
• For fuel level sensor inspection (page 21-19).
