(5) Start the engine and run at idle.
(6) Check that engine idle speed is within the standard value.
Curb idle speed: 750 f 100 r/min
(7) Turn the ignition switch to OFF.
(8) Remove the waterproof connector from the ignition timing
adjustment connector (brown).
(9) Connect the jumper wire to the ignition timing adjustment
terminal, and to a good ground as illustrated.

HC concentration: 100 ppm or less
(7) If the standard value is exceeded, check the following
items.

If CO and HC concentrations exceed the respective standard
values despite the fact that the results of the inspection
made on all items are normal, replace the three-way catalyst.

COMPRESSION PRESSURE INSPECTION
110003018
(1) Before inspection, check that the engine oil, starter and
battery are normal. Also, verify to the following conditions:
a Engine coolant temperature: 80-95°C (176-203°F)
a Lights, electric cooling fan and all accessories: OFF
a Transaxle: Neutral (P range on vehicle with A/T)
(2) Remove all of the spark plugs.
(3) Disconnect the 6-pin distributor connector (except 1995
models for California) or crankshaft position sensor connector (1995 models for California).
NOTE
Doing this will prevent the engine control module from
carrying out ignition and fuel injection.
(4) Cover the spark plug hole with a shop towel etc., and
after the engine has been cranked, check that no foreign
material is adhering to the shop towel.

Caution
1. Keep away from the spark plug hole when cranking.
2. During a compression test, if water, oil, fuel, etc.,
.
has come from cracks inside the cylinder, these
materials will become heated and will gush out
from the spark plug hole, which is dangerous.
(5) Set compression gauge to one of the spark plug holes.
(6) Crank the engine with the throttle valve fully open and
measure the compression pressure.
Standard value (at engine speed of 250-400 rlmin):
1,350 kPa (192 psi)
Limit (at engine speed of 250-400 r/min):
min. 960 kPa (137 psi)
(7) Measure the compression pressure for all the cylinders.
Verify difference between maximum and minimum readings do not exceed the limit.
Limit: max. 100 kPa (14 psi)
..--
(8) If there is a cylinder with compression or a compression
difference that is outside the limit, pour a small amount
of engine oil through the spark plug hole, and repeat the
operations in steps (6) and (7).
a. If the compression increases after oil is added, the
cause of the malfunction is a worn or damaged piston
ring and/or cylinder inner surface.
b. If the compression does not rise after oil is added,
the cause is a burnt or defective valve seat, or pressure
is leaking from the gasket.
(9) Connect the distributor connector (except 1995 models
for California) or crankshaft position sensor connector
(1995 models for California).
(1O)lnstall the spark plugs and spark plug cables.
(11)Use the scan tool to erase the diagnostic trouble codes,
or disconnect the battery ground cable for more than 10
seconds and reconnect it.
NOTE
This will erase the diagnostic trouble code resulting from
the distributor connector being disconnected.

Caution
Always turn the crankshaft clockwise.
(8) Turn the crankshaft clockwise to bring the No. 1 cylinder
piston to top dead center on the compression stroke.
Caution
For aligning the timlng marks, never turn the crankshaft counterclockwise as it could cause inadequate
belt tensioning.

F A 4 TIMING BELT INSTALLATION
(1) Align the timing marks on the camshaft sprocket and
crankshaft sprocket. (Now the piston in No. 1 cylinder
is at the top dead center on the compression stroke.)
(2) Set the timing belt first on crankshaft sprocket and
then keeping the tension side of belt tight, set on
the camshaft sprocket.
Caution
If the timing belt is re-used, install so that the
arrow marked on it at time of removal is pointing
in the clockwise direction.
(3) Apply counterclockwise force (in the direction B) to
the camshaft sprocket to give tension to the belt on
tension side and make sure that all timing marks are
lined up.
(4) Install the crankshaft pulley temporarily. This is to prevent the belt from coming off when crankshaft is turned.
