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-

!@ Do not smoke during this procsdura. Keep
any open tlame away from your work area.
1. Start the engine. Hold the engine at 3,000 rpm with
no load (in Park or neutral) until the radiator fan
comes on, then let it idle,
Connect a tachometer.
Check and, if necessary, adjust the idle speed, (see
page 11-169, 170).
Warm up and calibrate the CO meter according to the
meter manufacturer's instructions.
Check idle CO with the headlights, heater blower, rear
window defogger, cooling fan, and air conditioner off.
(Canada) Pull the parking brake lever up. Start the
engine, then check that the headlights are off.
CO meter should indicate 0.1% maximum.
