Removal
CAUTION: This vehicle uses a sequential multiport fuel injected engine. The fuel injector connectors must be connected to their appropriate fuel injector, or engine performance and exhaust emissions may be seriously affected. The fuel injector connectors are numbered to match their correct fuel injector for that cylinder.1. Disconnect the negative battery cable.
2. Relieve the fuel system pressure. See Powertrain Management.
3. Drain the coolant. See Cooling System.
4. Disconnect the Intake Air Temperature (IAT) sensor connector.
5. Remove the air intake duct from the throttle body and Mass Airflow (MAF) sensor.
6. Disconnect the clips attaching the fuel lines to the throttle body linkage cover.
7. Disconnect the wiring harness connectors from the fuel injectors.
8. Disconnect the clips attaching the wiring harness to the fuel rail.
9. Lay the left and the right wiring harnesses aside.
10. Remove the accelerator control/cruise control servo cable adjuster, if equipped.
11. Remove the accelerator bracket and the accelerator cables from the throttle body.
12. Remove the secondary air injection diverter valve hoses.
13. Remove the fuel pipe connectors from the fuel rail.
14. Remove the fuel rail bolts.
15. Remove the fuel pressure regulator vacuum tube.
16. Remove the fuel rail from the intake manifold and lay aside.
17. Remove the EGR valve vacuum harness.
18. Remove the crankcase vent hose.
19. Remove the Exhaust Gas Recirculation (EGR) control valve relay nut and control valve relay.
20. Remove the emission canister purge solenoid bracket nut and the solenoid.
21. Remove the EGR valve nuts and the valve.
22. Remove the EGR valve pipe nut and the stud.
23. Remove the secondary air injection pipe from the right exhaust manifold.
24. Remove the generator rear brace. See Starting and Charging.
25. Remove the coolant hoses from the throttle body.
26. Disconnect the connectors from the Throttle Position (TP) sensor and the Idle Air Control (IAC) valve.
27. Remove the following parts:
^ The throttle body bolts
^ The throttle body
^ The throttle body gasket
28. Remove the intake manifold bolts and studs.
29. Remove the intake manifold and the gaskets.
30. Discard the intake manifold gaskets.
31. Clean the following parts:
^ The intake manifold bolts and the studs
