4. Ground the ignition timing adjustment terminal.
5. Run the engine for more than 5 seconds at an engine speed of 2,000 to 3,000 rpm.
6. Run the engine at idle for 2 minutes.
7. Check that the engine rpm is within the standard value. If the scan tool is used, press code No. 22 and read the engine rpm.
Basic idle speed: 750 ± 100 rpm
NOTE: The engine speed on a new vehicle driven less than 300 miles may be 20 to 100 rpm lower than specification, but no adjustment is
necessary. If the engine stalls or the engine speed is low after the vehicle has been driven a distance of 300 miles or more, a deposit on the throttle
valve area is suspected.
8. If the basic idle speed is out of specification, adjust by the speed adjusting screw for the standard rpm. In adjusting use a tachometer.
NOTE: If the idle speed is higher than specified, even with the speed adjusting screw fully closed, check whether the idle switch moving mark
exists or not. If it is found that the switch has moved, adjust the idle switch.
9. Turn the ignition switch to the OFF position.

11. Disconnect the lead wire from the ignition timing adjusting terminals.
12. Run the engine again and let it idle for about 10 minutes. Check that the engine is in normal idling condition.
