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:

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.

(c) Disconnect the following connectors:
(1) Igniter connector
(2) California only:
Ignition coil connector
(3) Noise filter connector
(4) 2 ground straps from LH fender apron
(5) Connector from LH fender apron 12. DISCONNECT WIRES AND CONNECTORS
(a) Remove the engine relay box, and disconnect the 5
connectors.
(b) Connector from LH fender apron
(6) Data link connector 1
(7) 2 ground straps from RH fender apron
(d) Disconnect the MAP sensor connector.
13. DISCONNECT HEATER HOSES
14. DISCONNECT FUEL RETURN HOSE
CAUTION: Catch leaking fuel in a container.

2. CONNECT TACHOMETER 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 coil.
wAs some tachometers are not compatible with this
ignition system, we recommend that you confirm
the compatibility of yours before use.
3. INSPECT FUEL CUT RPM
(a) Increase the engine speed to at least 2,500 rpm.
(b) Use a sound scope to check for injector operating
noise.
(c) Check that when the throttle lever is released, injector
operation noise stops momentarily and then resumes.
HINT: Measure with the A/C OFF.
Fuel return speed:
1,500 rpm
