lgnition Timing Inspection and Setting
2.
1.Check the idle speed, and adjust it if necessary (see
section 1 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 (P/N 07PAz - 0010100) to
it.
Start the engine. Hold the engine at 3,000 rpm with
no load (A/T in N or E, Mff in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. I 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.

Loosen the distributor mounting bolts, and turn the
distributor ignition (Dl) housing counterclockwise to
advance the timing or clockwise to retard the tim-

Distributor Replacement
Removal:
1. Disconnect the connector from the distributor.
2. Disconnect the ignition wires from the distributor
ignition (Dl) cap.
3. Remove the mounting bolts from the distributor,
then remove the distributor from the cylinder head.

MOUNTING BOLTS8 x 1.25 mm2,1N.m {2.,1kgrf.m, 17 lbf ftl
lnstallation:
1. Bring the No. 1 piston to compression stroke TDC.
2. Coata new O-ring with engine oil, then install it.
3. Align the lug on the end of the distributor and its
mating grooves in the camshaft end, then slip the
distributor into position.
NOTE: The lug on the end of the distributor and its
mating grooves in the camshaft end are both offset
to eliminate the possibility of installing the distribu-
tor 180o out of time.
4. Installthe mounting bolts, and tighten them lightly.
5. Connect the ignition wires to the distributor ignition(Dl) cap as shown,
No. 1CYLINDERMARK
6. Connect the connector to the distributor.
7. Set the ignition timing (see previous page).
8. After setting the ignition timing, tighten the mount-
ing bolts.

Spark Plug Inspection
Inspect the electrodes and ceramic insulator for:
. lmproper gap. Oil-fouling. Carbon deposits. Cracked centerelectrode insulator
Burned or worn electrodes may be caused by:
. Advanced ignition timing
. Loose spark plug
. Plug heat range too hot
. Insufficient cooling
Fouled plug may be caused by:
. Retarded ignition timing
. Oil in combustion chamber
. Incorrect spark plug gap
. Plug heat range too cold
. Excessive idling/low speed runnang
. Clogged air cleaner element
. Deteriorated ignition wires
I
2. Check the electrode gaP.
. Adjust the gap with a suitable gapping tool.
Electrode Gap
Standard 1.1 3 ' mm (0.043 Loo. in)
Replace the plug if the center electrode is rounded
