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
