Inspoction/Adiustment
NOTE:
a When the idle speed set, check the following items:
- The MIL has not been reported on.- lgnition timing- Spark plugs- Air cleaner- PCV svstem
a (Canada) Pullthe parking brake lever up. Stan the en-
gine, then check that the headlights are off.
1 Start the engine. Hold the engine at 3,000 rpm with
no load (A/T in S or @ position, M/T in neutral)
until the radiator tan comes on, then let it idle.
2. Connect a tachometer.
3. Disconnect the 2P connectot trom the ldle Air Con-
trol {lAC) valve.
Start the engine with the sccelerator pedal slightly
depressed. Stabilize the rpm at 1 ,OOO, then slowly
release the pedal until the engine idles.
Check idling in no-load conditions: headlights, blower
fan, rear defogger, radiator fan, and ai. conditioner
are not operatrng.

Adjust the idle speed, if necessary, by turnmg the
idle adiusting screw.
NOTE: After adiust the idle speed in this step, check
the ignition timing (see section 231.
lf it is out ot spec. go back to step 4.

Turn the ignition switch OFF.
Reconnect the 2P connector on the IAC valve, then
remove the BACK UP (7.5 A) fuse in the under-hood
tuse/relav box for 1O seconds to reset the ECM.
Restart 8nd idle the engine with no-load conditions
for one minute, then check the idle speed.
NOTE: (Canada) Pull the parking brake lever up.
Start the engine, then check that the headlights ate
off.

Spark Plug Inspection
1. Inspect the electrodes and ceramic insulator for:
. rmproper gap. Oil-touling. Carbon deposits. Cracked centerelectrode insulatorDamagedgask6t
Burned or worn electlodes may be caused by:. Advanced ignition timing. Loose spark plug. Plug heat range too low. Insufficient cooling
Fouled plug may be caused by:. Retarded ignition timing. Oil in combustion chamber. lncorrect spark plug gap. Plug heat range too high. txcessive idling/low speed running. Clogged air cleaner element. Deteriorated ignition coil or ignition wires
Check the electrode gap.
Bl88l engine:
a Adjust the gap with a suitable gapping tool.
Electrode Gap
Standard: 1.0-1.1 mm (O.O39-0.O43 in)
1.1 mm{0.0,$ in)
Replace the plug if the center electrode is round-
ed as shown below:
ROUNDEDELECTROOE
Bl8Cl engine:
a Make sure that the '1.4 mm (0.055 in) wire-typeplug gauge does not go into the gap for the plati-
num tip plug. lf the gauge goes into the gap, do
not attempt to adjust the side electrode; replace
the plug with a new one. Use only the spark plugs
listed below.
ROUNDEO ELECTRODE
Electrode GapStandard: 1 .2-'l .3 mm{0.047 -O.051 in)Service Limit: 1.4 mm{0.055 in)
CAUTION: Do not use a blade-type plug gaugs, it
may damage the platinum tip of the center olectrodo.

3. Apply a small quantity ol anti-seize compound to the
plug threads.
Screw the plugs into the cylinder head iingef-tight,
then torque them to 18 N.m (1.8 kgf.m, 13lbf.ft).
