Removal

FUEL INJECTOR REMOVAL
1. Disconnect negative (-) terminal cable from battery.

CAUTION: Work must be started after 90 seconds from the time the ignition switch is turned to the LOCK position and the negative (-) terminal cable is disconnected from the battery.

2. Remove air cleaner cap.

(a) Disconnect the following connector, cord, cables and hoses:
(1) Intake air temperature sensor connector
(2) California only: High-tension cord from air cleaner hose
(3) Accelerator cable from clamp
(4) Cruise control actuator cable from clamps
(5) California only: Air hose for idle-up from air cleaner hose
(b) Disconnect the 4 clamps. and disconnect the air cleaner cap from the air cleaner case.
(c) Loosen the hose clamp, and disconnect the air cleaner hose from the throttle body.
(d) Remove the air cleaner cap and air cleaner hose assembly.

3. Disconnect control cables from throttle body

(a) Disconnect the following cables:
(1) Accelerator cable
(2) A/T throttle control cable

4. Disconnect throttle body from intake manifold

(a) Disconnect the following hoses:
(1) Vacuum hose (from upper port of TVV for EVAP) from port "P" of throttle body
(2) Vacuum hose (from port "Q" of EGR vacuum modulator) from port "E" of throttle body
(3) Vacuum hose (from port "R" of EGR vacuum modulator) from port "R" of throttle body
(4) PCV hose (from cylinder head) from throttle body

(b) Type A: Remove the 4 bolts.
(c) Type B: Remove the 2 bolts and 2 nuts.
(d) Disconnect the throttle body from the intake manifold.
(e) Remove the gasket.

5. Remove cylinder head cover.

(a) Disconnect the 4 high-tension cords from the clamp on the cylinder Head Cover.
(b) Disconnect the high - tension cords at the rubber boot. Do not pull on the high-tension cords.

NOTICE: Pulling on or bending the cords may damage the conductor inside.

(c) Remove the 2 bolts, and disconnect the cable bracket from the intake manifold.
(d) Disconnect the accelerator cable from the clamp on the intake manifold.
(e) Disconnect the PCV hose from the intake manifold.

(f) Disconnect the engine wire protector from the 2 mounting bolts of the No.2 timing belt cover in the sequence shown.

(g) Remove the 4 nuts, grommets, cylinder head cover and gasket.

NOTICE: Cover the cylinder head with a clean cloth to prevent dirt, etc. getting into the cylinder head.

HINT: Arrange the grommets in the correct order, so that they can be reinstalled into their original positions. This minimizes any possibility of oil leakage due to reuse of the grommets in different positions.

6. Remove Delivery Pipe And injectors.

(a) Disconnect the vacuum sensing hose from the fuel pressure regulator.
(b) California only: Disconnect the air hose for the air assist system from the intake manifold port, and remove the air hose.

(d) Disconnect the 4 injector connectors.

(e) Disconnect the engine wire protector from the 2 brackets on the front side of the intake manifold.

(f) Remove the union bolt and 2 gaskets. and disconnect the fuel in let hose from the delivery pipe.
(g) Disconnect the fuel return hose from the return pipe.

(h) Remove the 2 bolts holding the delivery pipe to the cylinder head.

(i) Disconnect the delivery pipe from the 4 injectors, and remove the delivery pipe.
(j) Pull out the 4 injectors.
NOTICE: Be careful not to drop the injectors.

(k) Remove the 4 insulators (Except California) and 2 spacers from the intake manifold.

(l) California models only: Remove the 2 O-rings, insulator and grommet from each injector.

(m) Except California models: Remove the O-ring and grommet from each injector.
