High Engine Idle Speed (No Drop)

SYMPTOM - HIGH ENGINE IDLE SPEED (NO DROP)

NOTE: Disconnecting the battery will cause the idling speed data in the ISC to be returned to the initial idling speed, causing the idling speed to rise above 700 rpm. Should this happen, either carry out a driving test, including stop-go several times at a speed above 10km/h, or start the engine, idle for 30 seconds and then turn the engine off repeatedly. By doing this, idle data will be stored in the lSC and the idle rpm will be at specified value.
