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.

PI-e-conditions for inspection
0Engine coolant temperature: 85-95°C (185-205°F)
0Lights, electric cooling fan and accessories: OFF
l Transaxle: Neutral
(P for vehicles with an automatic
transaxle)l Steering wheel: Neutral position (vehicles with a power
steering)l Check ignition timing and adjust if necessary. Refer to
GROUP 8.
NOTEWith vehicles for Canada, the headlights and taillights, etc.
remain on even when the lighting switch is turned OFF, but thiscauses no problems during inspection.
