SERVICE ADJUSTMENT PROCEDURES

CURB IDLE SPEED INSPECTION
CautionNlIFiiAE
The improper setting (throttle valve opening) will increase
exhaust gas temperature at deceleration, reducing catalystlife greatly and deteriorating exhaust gas cleaning per-
formance. It also has effect on fuel consumption and
engine braking.
