4B•6 Fuel and exhaust systems - single-point fuel injection engines 11.7 Accelerator cable adjustment 1 Throttle lever to lost motion link clearance should be equal on each side 2 Adjuster nut 3 Adjuster locknut (Chapter 12) and prior to tightening the cable locknuts, adjust the cable as follows. Adjustment 7 With the pedal fully released, check that there is equal clearance on each side of the throttle lever at the lost motion link (see illustration) and no slack in the cable. Have an assistant fully depress the pedal and check that the throttle cam opens fully, then check that it returns to the at-rest position when released. 8 To adjust the cable, switch on the ignition and position the stepper motor by moving the cam only to open, and fully close the throttle. Note that it is essential for accurate positioning of the stepper motor that the accelerator pedal switch contacts remain closed, so that the ECU recognises the throttle movement as a command and indexes the stepper motor to 25 steps. 9 Slacken the adjuster locknut (upper nut), then tighten the adjuster (lower) nut until the clearance is equal on each side of the throttle 13.7 Disconnecting breather hoses from throttle housing lever at the lost motion link. Tighten the locknut without disturbing this setting. Recheck the adjustment and switch off the ignition. 12 Accelerator pedal - removal and refitting Refer to Section 10 in Part A of this Chapter. 13 Throttle housing - removal and refitting 2 Removal 1 Depressurise the fuel system. 2 Disconnect the battery negative terminal and remove the air cleaner assembly. 3 Examine the injector housing fuel pipe feed and return unions for signs of leakage, then wipe them clean. 4 Using a spanner to hold each adaptor, unscrew the pipe union nuts and release the fuel feed and return pipes from the adaptors. Plug each pipe and adaptor to minimise the loss of fuel and prevent the entry of dirt into the system. 5 Release the wire retaining clips then disconnect the wiring connectors from the injector housing, the throttle potentiometer and the stepper motor. 6 Slacken the accelerator cable locknuts and free the cable outer from its mounting bracket. Release the cable inner from the throttle cam. 7 Using a suitable pair of pliers, release the retaining clips and disconnect the breather hoses from the throttle housing (see illustration). 8 Slacken and remove the four nuts securing the throttle housing to the inlet manifold, then remove the throttle housing from the vehicle. Remove the throttle housing insulating spacer and examine it for signs of wear or damage, renewing it if necessary (see illustrations). 9 If leakage was detected from the feed and return pipes or their union nuts, check the sealing surfaces of the nuts and adaptors and 13.8a Lift throttle body assembly away from inlet manifold . . . 1689 Rover 214 & 414 Updated Version 09/97 renew the adaptor or the pipe assembly, as necessary. 10 If leakage is detected from the adaptors, unscrew each through one turn with a spanner, then through two turns by hand. If the adaptor is still a tight fit in the housing, the threads are damaged and the housing and adaptors must be renewed as a set. If the threads are sound, fit new sealing washers to the adaptors and refit them, tightening them to their specified torque wrench setting. Refitting 11 Refitting is a reverse of the removal sequence, noting the following: a) Ensure that the mating surfaces of the throttle housing and inlet manifold are clean then fit the insulating spacer. b) Tighten the throttle housing and fuel pipe union nuts to their specified torque settings. c) On completion, reconnect and adjust the accelerator cable. 14 Fuel injection system components - testing 5 1 If a fault appears in the engine management (ignition/fuel injection) system, first ensure that the fault is not due to poor maintenance. That is, check that the air cleaner filter element is clean, the spark plugs are in good condition and correctly gapped, and that the engine breather hoses are clear and undamaged. Also check that the throttle cable is correctly adjusted. If the engine is running very roughly, check its compression pressures, bearing in mind that possibly one of the hydraulic tappets might be faulty, producing an incorrect valve clearance. 2 If these checks fail to reveal the cause of the problem, the vehicle should be taken to a suitably-equipped Rover dealer for testing. A wiring block connector is incorporated in the engine management circuit into which a special electronic diagnostic tester can be plugged. The tester will locate the fault quickly and simply, thereby alleviating the need to test all the system components individually 13.8b . . . and remove throttle body gasket spacer
15.1 Disconnecting fuel feed and return pipes from injector housing which is a time consuming operation that carries a high risk of damaging the ECU. 3 If necessary, the system wiring and wiring connectors can be checked as described in Chapter 12. Ensure that the ECU wiring connectors have first been disconnected. 15 Fuel injection system components - removal and refitting 3 Injector housing Removal 1 Carry out the operations described in paragraphs 1 to 4 of Section 13 (see illustration). 2 Release the wire retaining clip and disconnect the wiring connector from the injector housing (see illustration). 3 Remove the four screws securing the injector housing to the throttle body, then lift off the injector housing and remove the gasket (see illustrations). 4 If leakage was detected from the fuel feed and/or return pipes, perform the checks described in paragraph 9 of Section 13. Refitting 5 Refitting is a reversal of the removal procedure, noting the following: 15.8a Remove screw then lift off injector connector cap . . . Fuel and exhaust systems - single-point fuel injection engines 4B•7 15.2 Disconnecting wiring connector from injector housing a) Ensure the injector and throttle housing mating surfaces are clean, then fit a new gasket. b) Apply thread locking compound (Rover recommend Loctite Screwlock or Nutlock) to the threads of the injector housing screws, then tighten them to the specified torque. c) Tighten the fuel pipe union nuts to the specified torque setting. Fuel injector Removal 6 Note that as a Rover replacement part, the injector is available only as part of the injector housing. Commence removal by depressurising the fuel system. 7 Disconnect the battery negative terminal then remove the air cleaner assembly. 8 Slacken and remove the injector connector cap retaining screw and lift off the connector cap. The injector can then be lifted out of the housing (see illustrations). Refitting 9 Refitting is the reverse of the removal procedure. Ensure that the connector cap makes good contact with the injector pins. Fuel pressure regulator 10 The fuel pressure regulator is available 15.8b . . . and withdraw injector 1689 Rover 214 & 414 Updated Version 09/97 15.3a Injector housing-to-throttle body screws (A), connector cap screw (B) and pressure regulator screws (C) 15.3b Remove injector housing from throttle body - noting gasket only as part of the injector housing assembly. Refer to paragraphs 1 to 5 for details on removal and refitting. Stepper motor Removal 11 Remove the injector housing as described in paragraphs 1 to 4. 12 Release the retaining clip and disconnect the stepper motor wiring connector (see illustration). 13 Remove the four stepper motor retaining screws and remove the stepper motor assembly from the throttle housing (see 15.12 Disconnecting stepper motor wiring connector 4B
