NOTICE
Do not remove, disassemble or adjust the main throttle sensor, subthrottle sensor, subthrottle valve actuator, throttle link mechanism and throttle body assy, because they are adjust or set surely at the manufacturer. Adjustment of these parts could result in poor performance, requiring replacement of the throttle body assy.
NOTE
Do not damage the insertion portions of the injectors when they are pulled out from the throttle body.


NOTE
NOTICE
Never drop the primary fuel injector especially on a hard surface. Such a shock to the injector can damage it.
