(1) Disconnect the volume air flow sensor connector.
(2) Disconnect the breather hose, purge hose, by-pass air hose and boost hose connections.
(3)Remove the air intake hose on the air cleaner cover side
and then move the air intake hose to the front of the air
cleaner body.
(4) Unclamp the air cleaner cover.
Caution
Care must be taken when removing the air cleaner
cover, because the volume air flow sensor is at-
tached.
(5) Take out the air cleaner element.
(6) Check the air cleaner element for dirt or clogging; if necessary, clean by using compressed air.
(7) Replace the air cleaner element if the dirt or clogging
is
serious.
(8) Insert the element into the air cleaner body and install the air cleaner cover.
(9) Install the air intake hose.

4. SPARK PLUGS (Replace)
h%OSAOFa
1. Spark plugs must spark properly to assure proper engine performance and reduce exhaust emission
level.
Therefore, they should be replaced periodically with
new ones.
2. The new plugs should be checked for the proper gap.
Spark plug gap:
mm (.039-.043
in.)
0.7-0.8 mm (.028-.031 in.)
3.Install the spark plug and tighten to 20-30 Nm (15-21
ftlbs.).
5. TIMING BELT (Replace)moossAsa
Replace the belt with a new one periodically to assure
proper engine performance.
For disassembly and reassembly procedures, refer to
GROUP 11 -Service Adjustment Procedures.

(3) If any abnormal noise IS not eliminated by racing, check the
lash adjuster.
@ Stop the engine.
@ Set the engine so that cylinder No. 1 is positioned at
the top dead centre of the compression.
@ Press the rocker arm at the area indicated by the+ arrow mark to check whether the rocker arm is lowered
or not.
@ Slowly turn the crankshaft 360 degrees clockwise.
@ In the same procedure as Step 0, check the rocker
arm at the area indicated by the
0 arrow mark.
@ If the rocker arm lowers easily when the part directly
above the rocker arm lash adjuster is pressed, the lash
adjuster is defective and must be replaced. When re-
placing the lash adjuster, bleed the air from all adjus-
ters and then assemble them. Then inspect with proce-
dures
@ to 0, and confirm that there are no abnormal-
ities
NOTE
lThe lash adjuster can be accurately checked for de-
fects with the leak down test.
l Refer to the engine service manual for the leak down test and lash adjuster air bleeding procedure.
If the rocker arm is extremely hard when pressed
down, the lash adjuster is normal, so look for a different
cause of abnormal sound.
COMPRESSION PRESSURE CHECK
MllFFAL
(1) Before inspection, verify that the engine oil, starter motor and battery are normal. Then, perform the following.
l Engine coolant temperature:
80- 95°C
(176- 203°F)
l Lights, electric cooling fan and accessories: OFF
l Transaxle:
P range
0 Steering wheel: Neutral position
(2) Disconnect the spark plug cable.
(3) Remove all the spark plugs
(4) Disconnect the connector of the distributor.
NOTE
This will prevent the engine control module from controll- ing the ignition and fuel injection.

(3) Remove the PCV hose from the PCV valve and attach a
vacuum gauge.
(4) Check that the negative pressure at the intake manifold
during idle revolution is normal.
Standard value:
