Throttle body assembly
Removal 1 Remove the air cleaner and inlet air duct as described in Section 2. 2 Disconnect the wiring connectors from the throttle potentiometer, the idle control stepper motor and the inlet air temperature sensor. 3 Slacken the accelerator cable locknuts, then disengage the inner cable from the throttle cam and free the outer cable from its retaining bracket. Position the cable clear of the throttle body. 4 Unclip and disconnect the EVAP purge valve hose, and Ihe MAP sensor hose from the rear of the throttle body then, where applicable, disconnect the fuel pressure regulator vacuum hose from the front of the throttle body. 5 Slacken and remove the four bolts securing the throttle body assembly to the inlet manifold, then remove the assembly along with its insulating spacer. Refitting 6 Refitting is a reversal of the removal pro-cedure. bearing in mind the following points: 4! Examine the Insulating spacer for signs of damage, and renew If necessary. b) Ensure the throttle body, inlet manifold and insulating spacer mating surfaces are clean and dry, then fit the throttle body and spacer, and securely tighten the retaining bolts. c) Ensure ail hoses are correctly reconnected and, where necessary, /her their retaining clips are securely tightened. d) Adjust the accelerator cable as described in Section 4.

Fuel
rail and injectors
Removal 7 Disconnect the battery negative terminal (refer to Disconnecting tho battery in the Reference Section of this manual). 6 Remove the throttle body assembly as described earlier in this Section, however it is only necessary to move the unit to one side for access to the fuel rail and therefore it Is unnecessary to disconnect the accelerator caWe and hoses etc.
9 Depressurise Ihe fuel system as described in Section 9. 10 Loosen the clips or release the quick-release couplings and disconnect the fuel inlet and, on pre-1998 models, outlet hoses from the fuel rail. Note the fitted positions of the hoses to aid refitting later. 11 Unplug the ln}ector wiring harness connectors, labelling them to aid correct refitting later. 12 Unscrew the bolts securing the fuel rail assembly to the Inlet manifold, then carefully pull the Injectors from the Inlet manifold. Remove the assembly from the engine and remove the injector lower O-ring seals. 13 The injectors can be removed Individually from the fuel rail by extracting the relevant metal clip and easing Ihe injector out of the rail. Remove the injector upper O-ring seals (see illustration).
14 On pre-1998 models, if necessary remove the retaining clip and remove the fuel pressure regulator from the fuel rail. 15 Check the electrical resistance of the injector using a multimeter and compare It with the Specifications. Note: If a faulty Injector is suspected, before condemning the injector, It is worth trying the effect of one of the proprietary injector-cleaning treatments. Refitting 16 Refit the injectors and fuel rail by following the removal procedure, in reverse, noting the following points: a) Renew the injector O-rlng seals, and smear them with a little Vaseline before assembling. Take care when fitting the injectors to the fuel rail and do not press them in further than required to fit the retaining clip otherwise the O-ring seal may be damaged.

Warning: The following procedure will merely relieve the pressure In the fuel system • remember that fuel will still be present In the system components and take precautions accord-ingly before disconnecting any of them. 1 The fuel system referred to in this Section is defined as the lank-mounted fuel pump, tha fuel filter, the fuel rail, the fuel injectors, and the metal pipes and flexible hoses of the fuel lines between these components. All these contain fuel which will be under pressure while the engine Is running and/or while the Ignition is switched on. The pressure will remain for some time after the Ignition has been switched off. and must be relieved before any of these components are disturbed for servicing work. 2 Disconnect the battery negative terminal (refer to Disconnecting the battery In the Reference Section of this manual). 3 Have a large rag ready to cover the union to be disconnected and, if possible, place a con-tainer beneath the relevant connection/union. 4 Slowly loosen the connection or union nut (as applicable) to avoid a sudden release of pressure, and ensure that the rag is wrapped around the connection to catch any fuef spray which may be expelled. Once the pressure is released, disconnect the fuel line, and Insert plugs to minimise fuel loss and prevent the entry of dirt Into the fuel system. Note that on later models, quick-release fuel couplings are used on many of the fuel line connections. To release these couplings, depress the two clips on the side of the coupling while keeping the fuel line pushed In. With the clips depressed, slowly withdraw the fuel line from the coupling allowing the fuel pressure to release, then withdraw the fuel line fully.
