1990 MITSUBISHI SPYDER air condition

If not within the standard value range, turn the engine
speed adjusting screw to make the necessary adjustm ent.
NOTE
If the idling speed is higher standard value
even when the engine speed adjusting screw’ fully
closed, check whether or not there is any indicatio n that
the fixed SAS has been moved. If there
indication
that it ‘has been moved,
the fixed SAS. If there;
are no indications that it has been moved, it
possible
that there is leakage as a result
of the
fast idle air valve (FIAV), and, if so, the throttl e body
should be replaced.
7.Press the scan tool clear key, and release the motor
from the Actuator test‘ mode.
NOTE
Unless the motor is the Actuator test mode.
will continue 27 minutes.
8. Switch the ignition switch.
9. Disconnect the scan tool. 10. Start the engine again and let it run at idle s peed for
about 10 minutes; check to be the condition
is normal.
