52. Intake Manifold Assemble

Important: The following steps are only necessary if the throttle body or intake manifold required replacement.





1. Make sure all mating surfaces for the throttle body spacer (1) and throttle body are clean. Any debris or flawed sealing surfaces could cause vacuum leaks and hinder engine performance.

Notice: Refer to Fastener Notice in Service Precautions.

2. Install the throttle body spacer retaining bolts (2) and throttle body spacer (1) to the intake manifold.
^ Tighten the throttle body spacer bolts to 12 Nm (106 inch lbs.).





3. Install a new throttle body gasket (1) on the throttle body (3). Make sure all the old gasket material is removed.





4. Place the throttle body (4) in position on the throttle body spacer (1) and install the upper (2) and lower (3) throttle body retaining bolts.
4.1. Tighten the upper throttle body retaining bolts to 12 Nm (106 inch lbs.).
4.2. Tighten the throttle lower throttle body retaining bolts to 10 Nm (89 inch lbs.).





5. Press the MAP sensor in position at the top of the spacer mounting location.





6. Align the fuel rail snap lock retainers and fuel injectors in position on the intake manifold.

Important: DO NOT force the injector into position or damage to the O-ring seals could occur.





7. Snap the entire fuel rail and injector assembly into the intake manifold by pressing the fuel rail and injector simultaneously into correct position. Keep the fuel rail ground wire (1) clear of the injectors.





8. Connect the fuel regulator vacuum tube.





9. Place the fuel injector wire harness in position and connect each connector to its respective fuel injector.





10. Install the brake booster vacuum hose.
