-lgnition Timing Inspection and Setting
1.Check the idle speed, and adjust it it necessary (see
section 'l '1 ).
Pull out the service check connector 2P (BRN and BLK
wires) from the connector holder located under the
dash on the front passenger side, then connect the
SCS service connector (T/N 07PAZ - 0010'100) to it.
Start the engine. Hold the engine at 3.000 rpm with
no load {A,/T in E or E. M/T in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. 1 ignition wire,
then point the light toward the pointer on the timing
belt cover.
Check the ignition timing in no load conditions:
headlights. blower fan, rear window defogger, and
air conditioner are not operating.

6. Adjust the ignition timing if necessary, as follows.
Loosen the distributor mounting bolts. and turn the
distributor ignition (Dl) housing counterclockwise to
advance the timing, or clockwise to retard the tim-
ing.
MOUNTING BOLTS18 N'm (1.8 kgfm, 13lblftl
Tighten the distributor mounting bolts, and recheck
the ignition timing.
Disconnect the SCS service connector from the ser-
vice check connector.

Burned or worn electrodes may be causecl by:
. Advanced ignition timing
. Loose spark plug
. Plug heat range too low
. Insufficient cooling
Fouled plugs may be caused bY:
. Retarded ignition timang
. Oil in combustion chamber
. Incorrect spark plug gap
. Plug heat rangetoo high
. Excessive idling/low speed running
. Clogged air cleaner element
. Deteriorated ignition coil or ignition wares
