2. CONNECT TACHOMETER AND TIMING LIGHT TO
ENGINE
Connect the test probe of a tachometer to terminal IG
(±) of the data link connector 1.
NOTICE:
wNEVER allow the tachometer terminal to touch
ground as it could result in damage to the igniter
and/or ignition coif.
wAs some tachometers are not compatible with this
Ignition system, we recommend that you confirm
the compatibility of yours before use.
3. ADJUST IGNITION TIMING
(a) Using SST, connect terminals TE1 and E1 of the data
link connector 1.
SST 09843±18020
HINT: After engine speed is kept at 1,000 ± 1,300
rpm for 5 seconds, check that it returns to idle speed.
IGNITION TIMING INSPECTION AND
ADJUSTMENT
1. WARM UP ENGINE
Allow the engine to warm up to normal operating
temperature.
(b) Using a timing light, check the ignition timing.
Ignition timing:
10
BTDC @ idle
(Transmission in neutral position)

4. FURTHER CHECK IGNITION TIMING
Ignition timing:
0 ± 10 BTDC @ idle
(Transmission in neutral position)
HINT: The timing mark moves in a range between 0
and 10. (c) Loosen the bolt (California) or 2 bolts (except Califor±
nia), and adjust by turning the distributor.
(d) Tighten the bolt (California) or 2 bolts (except Califor±
nia), and recheck the ignition timing.
Torque: 19 N±m (195 kgf±cm, 14 ft±lbf)

IDLE SPEED INSPECTION
1. INITIAL CONDITIONS
(a) Engine at normal operating temperature
(b) Air cleaner installed
(c) All pipes and hoses of air induction system connected
(d) All vacuum lines properly connected
(e) MFI/SFI system wiring connectors fully plugged
(f) All operating accessories switched OFF
(g) Ignition timing set correctly
(h) Transmission in neutral position
2. CONNECT TACHOMETER
Connect the test probe of a tachometer to terminal IG
(±) of the data link connector 1.
NOTICE:
wNever allow the tachometer terminal to touch
ground as it could result in damage to the Igniter
and/or ignition coil.
wAs some tachometers are not compatible with this
ignition system, we recommend that you confirm
the compatibility of yours before use.
(b) Check the idle speed.
Idle speed (w/ Cooling fan OFF):
750+50 rpm
If the idle speed is not as specified, check the IAC
system.
4. DISCONNECT TACHOMETER 3. INSPECT IDLE SPEED
(a) Race the engine at 2,500 rpm for approx. 90 seconds.

IDLE AND OR 2,500 RPM CO/HC
CHECK
HINT: This check is used only to determine whether or
not the idle CO/HC complies with regulations.
1. INITIAL CONDITIONS
(a) Engine at normal operating temperature
(b) Air cleaner installed
(c) All pipes and hoses of air induction system connected
(d) All accessories switched OFF
(e) All vacuum lines properly connected
HINT: All vacuum hoses for EGR systems, etc. should
be properly connected.
(f) MFI/SFI system wiring connectors fully plugged
(g) Ignition timing set correctly
(h) Transmission in neutral position
(i) Tachometer and CO/HC meter calibrated by hand.
4. INSERT CO/HC METER TESTING PROBE AT LEAST
40 cm (1.3 ft) INTO TAILPIPE DURING IDLING
5. IMMEDIATTELY CHECK CO/HC CONCENTRATION
AT IDLE AND/OR 2,500 RPM
Complete the measuring within 3 minutes.
HINT: When performing the 2 mode (2,500 rpm and
idle) test, follow the measurement order prescribed by
the applicable local regulations. 2. START ENGINE
3. RACE ENGINE AT 2,500 RPM FOR APPROX. 180

Troubleshooting
If the CO/HC concentration does not comply with
regulations, perform troubleshooting in the order
given below.
(a) Check oxygen sensor operation.
(See page EG1±231)
(b) See the table below for possible causes, then inspect
and correct the applicable causes if necessary.
1. Faulty ignitions:
wIncorrect timing
wFouled, shorted or improperly gapped plugs
wOpen or crossed high±tension cords
wCracked distributor cap
2. Incorrect valve clearance
3. Leaky EGR valve
4. Leaky intake and exhaust valves
5. Leaky cylinder
