DISASSEMBLY
• The throttle body/sensor unit is factory pre-set.
Do not disassemble in a way other than shown in
this manual.
• 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.
• Do not damage the throttle body. It may cause
incorrect throttle valve operation.
• Do not loosen or tighten the white painted nut
and screw of the throttle body. Loosening or
tightening it can cause throttle valve and idle
control failure.
• Always clean around the throttle body before
each sensor removal to prevent dirt and debris
from entering the air passage.
Remove the injector (page 5-60).
