2. Disconnect intake duct from throttle body.

Dynamic Chamber To Manifold (Bolt Locations):

3. Remove intake manifold dynamic chamber and throttle body, as an assembly, from intake manifold.

4. Disconnect vacuum hoses and fuel hoses from fuel rail (fuel delivery pipe).

5. Disconnect electrical connectors from fuel injectors.

6. Remove fuel rail.

7. Remove injectors, O-rings, and insulators.

8. Install in the reverse order. Lubricate injecotr O-rings with gasoline prior to installation. Tighten dynamic chamber to manifold bolts to specified torque.
