Engine
NOTICE: Remove the cylinder heads before removing the crankshaft. Failure to do so may result in engine damage.
NOTICE: If the fuel rail is used as a leverage device, it may be damaged. Care must be taken when working around the fuel rail.
NOTE: During the repair or replacement of fuel-related components, cap, tape or otherwise appropriately protect all liquid and vapor fuel openings to prevent the ingress of dirt or foreign material. Remove all caps, tape and other protective materials prior to installation.
NOTE: For additional information, refer to the exploded views under Engine Engine - Assembly in the Assembly.

23. Disconnect the Electronic Throttle Body (ETB) and Throttle Position (TP) sensor electrical connectors. Remove the nut and detach the wiring harness bracket.
24. Remove the exhaust manifold-to-EGR system module tube.
25. NOTICE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.
Remove the 8 bolts and the intake manifold and 6 gaskets.
26. Disconnect the 6 fuel injector electrical connectors and detach the wiring harness retainers.
