1. Disconnect and isolate the negative battery cable.
2. Remove the engine cover (1).





3. Remove the resonator (1) Removal.





4. Disconnect the electrical connectors from the Manifold Absolute Pressure (MAP) sensor (1) and the Electronic Throttle Control (ETC) (7).
5. Disengage the ETC harness from the clip (8) on the throttle body. Disengage the wire harness retainers (4 and 5) from the upper intake manifold near the MAP sensor and reposition the wire harness.
6. Disconnect the following hoses from the upper intake manifold:
- Positive Crankcase Ventilation (PCV) (3)
- vapor purge (6)
- brake booster (2)





7. Disengage the wire harness retainer (4) from the upper intake manifold support bracket (5).
8. Disengage the wire harness retainer (3) from the studbolt (2).
9. Remove two nuts (1), loosen the studbolt (2) and reposition the upper intake manifold support bracket (5).





10. Remove the nut (2) from the support bracket of the heater core return tube (1).





11. Remove two nuts (1), loosen two studbolts (3) and reposition the two upper intake manifold support brackets (2).






NOTE: The upper intake manifold attaching bolts are captured in the upper intake manifold. Once loosened, the bolts will have to be lifted out of the lower intake manifold and held while removing the upper intake manifold.

NOTE: Exercise care not to inadvertently loosen the two fuel rail attachment bolts that are in close proximity of the upper intake manifold attaching bolts.

12. Remove seven manifold attaching bolts (1) and remove the upper intake manifold (2).





13. Remove and discard the six upper to lower intake manifold seals (1).
14. Cover the open intake ports to prevent debris from entering the engine.
