Removal and Installation

1. Perform fuel pressure release procedure. Service and Repair
2. Disconnect battery ground cable.
3. Remove upper intake manifold.
4. Disconnect fuel supply and return tubes from fuel injection supply manifold.
5. Disconnect fuel charging wiring from fuel injectors and valve cover retaining studs. Position fuel charging wiring aside.
6. Disconnect vacuum supply tube from fuel pressure regulator and Intake Manifold Runner Control (IMRC) actuator cable from bracket and lever and position aside.
7. If required, remove fuel injection supply manifold and fuel injectors from lower intake manifold (IMRC).
8. It required, remove bolts and remove IMRC actuator cable bracket from lower intake manifold.





9. Remove lower intake manifold to cylinder head retaining bolts in sequence.

Lower Intake Manifold:

10. Remove lower intake manifold (IMRC) from cylinder heads.
11. Remove intake manifold gaskets from cylinder heads and discard.

Tightening Sequence:

12. To install, reverse removal procedure using new intake manifold gaskets. Tighten lower intake manifold retaining bolts to 8-12 Nm (71-106 lb in) in sequence. If removed, tighten IMRC actuator bracket retaining bolts to 8-12 Nm (71-106 lb in). Connect fuel supply and return tubes.
