NO >> Follow the instruction of IDLE AIR VOLUME LEARNING. Then GO TO 4.
14.CHECK TARGET IDLE SPEED AGAIN
1. Start engine and warm it up to normal operating temperature.
2. Check idle speed.
For procedure, refer to EC-801, "Inspection".
For specification, refer to EC-807, "Idle Speed".
Is the inspection result normal? YES >> GO TO 15.
NO >> GO TO 17.
15.CHECK IGNITION TIMING AGAIN
