INSTALLATION
1. INSTALL INJECTORS AND DELIVERY PIPE
(a) Install a new grommet to the injector.
(b) Apply a light coat of gasoline to a new O −ring and install
it to the injector.
(c) While turning the injector left and right, install it to the de-
livery pipe. Install the 6 injectors.
(d) Position the injector connector upward.
(e) Place 6 new insulators and the 3 spacers in position on the intake manifold.
(f) Place the 6 injectors together with the delivery pipe in position on the intake manifold.
(g) Temporarily install the 3 bolts holding the delivery pipe to
the intake manifold.
(h) 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.
(i) Position the injector connector upward.
(j) Tighten the 3 bolts holding the delivery pipe to the intake manifold.

THROTTLE BODY
ON−VEHICLE INSPECTION
1. INSPECT THROTTLE BODY
(a) Check that the throttle linkage moves smoothly.
(b) Check the vacuum at each port.
Start the engine.
Check the vacuum with your finger.

PNo vacuumVacuum
ENo vacuumVacuum
RNo vacuumVacuum
2. INSPECT THROTTLE POSITION (TP) SENSOR
(a) Disconnect the TP sensor connector.
(b) Apply vacuum to the throttle opener.
(c) Using an ohmmeter, measure the resistance between
each terminal.

(d) Reconnect the TP sensor connector.
3. INSPECT AND ADJUST DASHPOT
(a) Allow the engine to warm up to normal operating tempera-
ture.
(b) Check the idle speed.
Idle speed: 650 ± 50 rpm (N position)
(c) Open the throttle valve until the throttle lever separates from the dashpot end.
(d) Release the throttle valve gradually, and check the dash-
pot setting speed when the throttle lever touched the
dashpot end.
Dashpot setting speed: 2,200 ± 300 rpm

If not as specified, adjust using the following procedure:
(1) Stop the engine.
(2) Loosen the lock nut of the stopper bolt.
(3) Adjust the dashpot setting speed by turning thestopper bolt.
(4) Start the engine and check the dashpot setting speed.
(5) Retighten the lock nut.
(e) Maintain the engine at 3,500 rpm.
(f) Release the throttle valve, and check that the engine re- turns to idle in a few seconds.
4. CHECK THROTTLE OPENER
(a) Disconnect the vacuum hose from the throttle opener, and plug the hose end.
(b) Check the throttle opener setting speed. Throttle opener setting speed: 700 − 1,000 rpm
If the throttle opener setting is not as specified, replace the
throttle body.
(c) Stop the engine.
(d) Reconnect the vacuum hose to the throttle opener.
(e) Start the engine, and check that the idle speed returns to the correct speed.
Idle speed: 650 ± 50 rpm (N position)

INSPECTION
1. CLEAN THROTTLE BODY
(a) Using a soft brush and carburetor cleaner, clean the cast parts.
(b) Using compressed air, clean all the passages and aper- tures.
NOTICE:
To prevent deterioration, do not clean the throttle position
sensor, dashpot and IAC valve.
2. INSPECT THROTTLE VALVE

(b) Check that there is no clearance between the throttle stop
screw and throttle lever when the throttle valve is fully
closed.
3. INSPECT THROTTLE POSITION SENSOR
(a) Apply vacuum to the throttle opener.
(b) Insert a 0.50 mm (0.020 in.) or 0.75 mm (0.030 in.) feeler
gauge between the throttle stop screw and stop lever.
(c) Using an ohmmeter, measure the resistance between
each terminal.
