Installation
PROCEDURECAUTION: After affecting any repair that requires disassembly of fuel related components, inspect carefully for fuel leaks upon completion.
1. Install Injectors and Delivery Pipe.
- Install new grommets to each Injector. Apply a light coat of gasoline to new O-rings and install them to each Injector (see diagram).
- While turning the Injector clockwise and counterclockwise, push it to the Delivery Pipe. Install the 6 Injectors.
- Position the Injector connector outward.
- Place the 6 insulators (Except California) and 3 spacers in position on the intake manifold.
- Place the 6 Injectors together with the Delivery Pipe and 3 bolts in position on the intake manifold.
- Temporarily install the 3 bolts holding the Delivery Pipe to the intake manifold.
- Check that the Injectors rotate smoothly. HINT: If Injectors do not rotate smoothly, the probable cause is incorrect installation of O-rings. Replace the O-rings.
- Position the Injector connector upward.
- Tighten the 3 bolts holding the Delivery Pipe to the intake manifold.
Torque: 21 Nm (15 ft lb)
2. Install the actuator for Acoustic Control Induction System with the 2 bolts.
Torque: 6.8 Nm (61 in lb)
3. Connect Injector connectors.
NOTE: The No. 1, No. 3 and No. 5 Injector connectors are dark gray, and the No. 2, No. 4 and No. 6 Injector connectors are gray.
4. Connect vacuum sensing hose.
5. Install air intake chamber stays with the bolt and nut. Install the No. 1 and No. 2 stays. The No. 1 stay is marked with "F" and No. 2 stay is marked with "R".
Torque: 18 Nm (13 ft lb)
6. Connect no. 2 fuel pipe to Fuel Pressure Regulator with 2 new gaskets and the union bolt.
Torque: 27 Nm (20 ft lb)
- Install the bolt holding the fuel pipe to the intake manifold.
7. Connect no.1 fuel pipe to Delivery Pipe with 2 new gaskets and the union bolt.
Torque: 42 Nm (30 ft lb)
- Install the No. 2 vacuum pipe with the 2 nuts.
Torque: 21 Nm (15 ft lb)
8. Install Throttle Body with intake air connector.
- Place the gasket so the protrusion face the intake chamber, and set the Throttle Body together with the intake air connector.
- Connect the 2 water bypass hoses to the Throttle Body.
- Connect the vacuum hose (from the actuator) to the No. 1 vacuum pipe.
- Install the intake air connector with the 4 bolts and 2 nuts.
Torque: 21 Nm (15 ft lb)
- Install the nut holding the Vacuum Switching Valve to the chamber stay.
- Connect the following connectors:
Sub-Throttle Actuator connector (w/TRAC) (1).
Sub-Throttle Position Sensor connector (w/ TRAC) (2).
Idle Air Control Valve connector (3).
Throttle Position Sensor connector (4).
Vacuum Switching Valve for Exhaust Gas Recirculation connector (5).
- Connect the following hoses:
Positive Crankcase Ventilation hose to intake air connector (1).
3 vacuum hoses to No. 2 vacuum pipe (2).
9. Install Throttle Body bracket with the 4 nuts.
Torque: 21 Nm (15 ft lb)
10. Connect Exhaust Gas Recirculation Gas Temperature Sensor connector (California only).
11. Install Exhaust Gas Recirculation pipe.
- Temporarily install the union nut of the Exhaust Gas Recirculation pipe.
- Install a new gasket and the Exhaust Gas Recirculation pipe with the 2 bolts.
Torque: 21 Nm (15 ft lb)
- Tighten the union nut of the Exhaust Gas Recirculation pipe.
Torque: 64 Nm (47 ft lb)
12. Install intake air connector pipe.
- Install the air connector pipe with the 2 hose clamps.
- Connect the following hoses:
PS air hose to air connector pipe (1).
PCV hose to No. 2 cylinder head cover (2).
13. Connect the following control cables to Throttle Body.
Accelerator cable (1)
A/T throttle control cable (2)
Cruise control actuator cable (3)
14. Fill engine with coolant.
15. Connect cable to negative terminal of battery.
