Ignition Timing Check - Mitsubishi MOTORS Space Runner 1999 Workshop Manual Supplement

ENGINE <4G6-MPI> -
<When measuring the deflection>
Apply 98 N of pressure against the location between
the pulleys shown by the arrow in the illustration and
then measure the deflection.
2. If the tension or deflection is outside the standard value,
adjust by the following procedure.
(1) Loosen tensioner pulley fixing nut A.
(2) Adjust the amount of belt deflection using adjusting
(3) Tighten fixing nut A.
(4) Check the belt deflection amount and tension, and

IGNITION TIMING CHECK

1. Before inspection, set the vehicle to the pre-inspection
condition.
2. Connect the MUT-II to the diagnosis connector.
3. Set up a timing light.
4. Start the engine and run at idle.
5. Check that engine idle speed is within the standard value.
Standard value: 750 ± 100 r/min
6. Select No.17 of the MUT-II Actuator test.
7. Check that basic ignition timing is within the standard
value.
Standard value: 5_ BTDC±3_
8. If the basic ignition timing is outside the standard value,
inspect the MPI system while referring to GROUP 13A
- Troubleshooting.
9. Press the MUT-II clear key (Select a forced driving cancel
mode) to release the Actuator test.
Caution
If the test is not cancelled, a forced driving will
continue for 27 minutes. Driving under this condition
may damage the engine.
10. Check that ignition timing is at the standard value.
Standard value: approx. 10_BTDC
NOTE
1. Ignition timing is variable within about ± 7_, even
2. And it is automatically further advanced by about
