Injectors Installation
1. INSTALL INJECTORS AND DELIVERY PIPE.
- Install new insulator and grommet to each injector.
- Apply a light coat of gasoline to 2 new 0-rings. and install them to each injector.
- 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 and 3 spacers in position on the intake manifold.
- Place the 6 injectors together with the delivery pipe 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 0-rings.
- Replace the 0-rings.
- Position the injector connector upward.
- Tighten the 3 bolts holding the delivery pipe to the intake manifold.

- Place the throttle body and intake air connector assembly on the cylinder head.
- Connect these hoses:
- 3 vacuum hoses (from No.2 vacuum pipe) to No.1 vacuum pipe
- Water bypass hose (from water outlet) to throttle body
- Vacuum hose (from actuator for ACIS) to No.1 vacuum pipe
- Install the 4 bolts and 2 nuts holding the intake air connector to the air intake chamber.
Torque: 27 N.m (270 kgf.cm, 20 ft.lb.)
- Install the nut holding the VSV for the EGR to the air intake chamber.
- Connect these connectors and hoses:
- Throttle position sensor connector
- IAC valve connector
- VSV connector for EGR
- PCV hose to intake air connector
- Water bypass hose (from No.2 water bypass pipe) to throttle body
- Air hose to IAC valve
- w/TRAC:
Sub-throttle position sensor connector
