GENERAL MAINTENANCE
These are some maintenance and inspection items which are considered to be the owner's responsibility.
They can be done by the owner or they can have them done at a service shop. These items include those
which should be checked on a daily basis, those which, in most cases, do not require (special) tools and
those which are considered to be reasonable for the owner to do. Items and procedures for general mainte-
nance are as follows.
1. GENERAL NOTES

Maintenance items may very from country and country. Check the owner's manual supplement in
which the maintenance schedule is shown.

Every service items in the periodic maintenance schedule must be performed.

Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).

Maintenance service after the last period should be performed at the same time interval as before un-
less otherwise noted.

Failure to do even one item an cause the engine to run poorly and increase exhaust emissions.
2. TIRES
(a) Check the pressure with a gauge. If necessary, adjust.
(b) Check for cuts, damage or excessive wear.
3. WHEEL NUTS
When checking the tires, check the nuts for looseness or for missing nuts. If necessary, tighten them.
4. TIRE ROTATION
Check the owner's manual supplement in which the maintenance schedule is shown.
5. WINDSHIELD WIPER BLADES
Check for wear or cracks whenever they do not wipe clean. If necessary, replace.
6. FLUID LEAKS
(a) Check underneath for leaking fuel, oil, water or other fluid.
(b) If you smell gasoline fumes or notice any leak, have the cause found and corrected.
7. DOORS AND ENGINE HOOD
(a) Check that all doors and the tailgate operate smoothly, and that all larches lock securely.
(b) Check that the engine hood secondary latch secures the hood from opening when the primary latch
is released.

INSTALLATION
1. INSTALL INJECTORS AND DELIVERY PIPES
NOTICE:

Be careful not to drop the injectors when installing
the delivery pipes.

Since the O-ring may be stuck to the injector, do not
put a side load on it at the removal.
(a) Install a new grommet to each injector.
(b) Apply a light coat of gasoline to new O-rings and install
them to each injector.
(c) While turning the injector clockwise and counterclock-
wise, push it to the delivery pipes. Install the 8 injectors.
(d) Position injector connector outward.
(e) Place the 4 spacers and 8 new insulators on the intake
manifold.
(f) Place the 2 delivery pipes and the injectors assemblies on
the lower intake manifold.
(g) Temporarily install the 4 nuts.
(h) Install the front fuel pipe with the bolt, the 4 new gaskets
and the 2 union bolts.
Torque:
39 N´m (400 kgf´cm, 29 ft´lbf) for union bolts
7.5 N´m (80 kgf´cm, 66 in.´lbf) for bolt
(i) Install the bolt holding the clamp on the fuel return pipe to
the LH delivery pipe.
Torque: 7.5 N´m (80 kgf´cm, 66 in.´lbf)
(j) Check that the injectors rotate smoothly.
HINT:
If injectors do not rotate smoothly, the probable cause is incor-
rect installation of O-rings. Replace the O-rings in that case.
(k) Position the injector connector outward.
(l) Tighten the 4 nuts holding the delivery pipes to the lower
intake manifold.
Torque: 21 N´m (214 kgf´cm, 15 ft´lbf)
(m) Connect the 8 injectors connectors.

PRECAUTION
1. BEFORE WORKING ON FUEL SYSTEM, DISCON-
NECT NEGATIVE (-) TERMINAL CABLE FROM BAT-
TERY
HINT:
Any diagnostic trouble code retained by the computer will be
erased when the negative (-) terminal cable is removed from
the battery.
Therefore, if necessary, read the diagnosis before removing the
negative (-) terminal cable from the battery.
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME
WHEN WORKING ON THE FUEL SYSTEM
3. KEEP GASOLINE AWAY FROM RUBBER OR
LEATH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) Take following precautions to prevent the engine misfire.
(1) Check proper connection to battery terminals, etc.
(2) After repair work, check that the ignition coil termi-
nals and all other ignition system lines are recon-
nected securely.
(3) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(b) Take following precautions to handle the oxygen sensor.
(1) Do not drop the oxygen sensor or hit against an ob-
ject.
(2) Do not allow the sensor to contact with water.
5. IF VEHICLE IS EQUIPPED WITH MOBILE RA-
DIO
SYSTEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
6. AIR INDUCTION SYSTEM
(a) Separation of the engine oil dipstick, oil filler cap, PCV
hose, etc. may cause the engine to be out of tune.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will cause air suction, which makes the engine out
of tune.
7. ELECTRONIC CONTROL SYSTEM
(a) Disconnect the power by either turning the ignition switch
OFF or disconnecting the negative (-) terminal cable from
the battery before removing SFI wiring connectors, termi-
nals, etc.
HINT:
Always check the diagnostic trouble code before disconnecting
the negative (-) terminal cable from the battery.
(b) When installing the battery, be especially careful not to in-
correctly connect the positive (+) and negative (-) cables.

(c) Do not a severe impact during removal or installation.
Handle all SFI parts carefully, especially the ECM.
(d) Be careful during the troubleshooting as there are numer-
ous transistor circuit, and even slight terminal contact can
cause further troubles.
(e) Do not open the ECM cover.
(f) When inspecting in rainy weather, take care to prevent
entry of water. Also, when washing the engine compart-
ment, prevent water from getting on the SFI parts and the
wiring connectors.
(g) Parts should be replaced as the original assembly.
(h) Care should be taken when pulling out and inserting the
wiring connectors.
(1) Release the lock and pull out the connector.
(2) Fully insert the connector and check that it is locked.
(i) Use SST for the inspection, the injector and the wiring
connector test.

8. FUEL SYSTEM
(a) When disconnecting the high fuel pressure line, a large
amount of gasoline may be spilled:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped on
its own, turn the ignition switch OFF.
(3) Put a container under the connection.
(4) Slowly loosen the connection.
(5) Disconnect the connection.
(6) Plug the connection with a rubber plug.
(7) Reconnect the fuel pump connector.
