Idle Speed: Adjustments
NOTE: Idle speed is set at the factory and readjustment should be unnecessary. Before adjusting basic idle speed confirm that the ignition system, the
Idle Speed Control Servo, the fuel injectors and the engine compression are all normal and within specification.
CAUTION: Improper setting of the throttle valve opening will increase exhaust gas temperatures at deceleration, which will greatly reduce the life of
the Catalytic Converter. Also, fuel consumption and engine braking will be affected.
