Intake Manifold Assembly

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





1. Align the fuel rail 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. Keep the fuel rail ground wire (1) clear of the injectors.

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






3. Place the fuel injector wire harness in position.
4. Connect each electrical connector to its respective fuel injector.





5. Connect the fuel regulator vacuum tube.





6. Install the brake booster vacuum hose.





7. 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 resulting in poor engine performance.
8. Install the throttle body spacer (1) and retaining bolts (2) to the intake manifold.
^ Tighten the throttle body spacer bolts to 12 Nm (106 in. lbs.).





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





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





11. Install the four throttle body retaining bolts (3).
^ Tighten the upper throttle body retaining bolts to 12 Nm (106 in. lbs.).
^ Tighten the lower throttle body retaining bolts to 10 Nm (89 in. lbs.)
