53. Intake Manifold Assemble
Important: The following steps are only necessary if the throttle body or intake manifold required replacement.
1. Align the snap lock retainers and fuel injectors in position on the intake manifold.
2. Snap the entire fuel rail and injector assembly into the intake manifold by pressing the fuel rail and injector simultaneously into correct position. DO NOT force the injector into position or damage to the O-ring seals could occur. Keep the fuel rail ground wire (1) clear of the injectors.
3. Connect the fuel regulator vacuum tube.
4. Place the fuel injector wire harness in position and connect each connector to its respective fuel injector.
5. Install the power brake booster vacuum hose.
Important: Make sure all mating surfaces for the throttle body spacer and throttle body are clean. Any debris or flawed sealing surfaces could cause vacuum leaks and hinder engine performance.
6. Install the throttle body spacer retaining bolts (2) and throttle body spacer (1) to the intake manifold.
Notice: Refer to Fastener Notice in Service Precautions.
- Tighten the throttle body spacer bolts to 12 Nm (106 lb in).
7. Press the MAP sensor in position at the top of the spacer mounting location.
8. Install a new throttle body gasket (1) on the throttle body (3). Make sure all the old gasket material is removed.
9. Place the throttle body (4) in position on the throttle body spacer (1).
10. Install the upper (2) and lower (3) throttle body retaining bolts.
- Tighten the upper throttle body retaining bolts to 12 Nm (106 lb in).
- Tighten the lower throttle body retaining bolts to 10 Nm (89 lb in).
