IDLE SPEED CHECK

2.Turn the ignition switch to the "LOCK" (OFF) position and then connect the M.U.T.-III to the diagnosis connector (Refer to GROUP 00 - Precautions Before Service, M.U.T.-III ).

3.Set the timing light to the terminal No. 3 power supply line (white) of the ignition coil No. 1. 4.Start the engine and let it run at idle. 5.Check that ignition timing is at the standard value. Standard value: approximately 10° BTDC note The ignition timing may fluctuate within ± 7°. This is normal. In higher altitude, the ignition timing is more advanced than the standard value by approximately 5°. Wait till approximately 1 minute passes after the engine started, and check the ignition timing when the engine stabilized. 6.Check the idle speed. Standard value: 720 ± 100 r/min note The idle speed is controlled automatically by the idle speed control system. When using the M.U.T.-III, select item No. 2 and take a reading of the idle speed. 7.If the idle speed is outside the standard value, inspect the MPI system (Refer to GROUP 13A - Troubleshooting - Inspection chart for trouble symptom ). 8.Remove the timing light. 9.Turn the ignition switch to the "LOCK" (OFF) position and then disconnect the M.U.T.-III.
