Throttle body - removal and refitting
Note: A tachometer and an exhaust gas analyser will be required to check the idle mixture on completion. A new gasket must be used when refitting the throttle body.
2.0 litre SOHC models
1 Disconnect the battery negative lead.
2 Free the throttle position sensor wiring plug from the retaining clip on the underside of the throttle body. Disconnect the wiring plug halves by releasing the locktabs and pulling on the plug halves, not the wiring.
3 Disconnect the throttle cable from the lever.
4 Disconnect the crankcase ventilation hose from the air inlet hose, then disconnect the air inlet hose from the throttle body and the airflow meter.
5 Remove the four securing bolts and withdraw the throttle body from the inlet manifold. Recover the gasket.
6 Refitting is a reversal of removal, bearing in mind the following points.
7 Ensure that all mating faces are clean, and fit a new gasket.
8 When reconnecting the air inlet hose, make sure that the hose clips are correctly aligned, see illustration, Section 15.
9 On completion, adjust the throttle cable and check and if necessary adjust the idle mixture.

10 Disconnect the battery negative lead.
11 Free the throttle position sensor wiring plug from the retaining clip located on the underside of the throttle body. Disconnect the wiring plug halves by releasing the locktabs and pulling on the plug halves, not the wiring.
12 Disconnect the throttle cable from the linkage.
13 Loosen the securing clip, and disconnect the air inlet hose from the throttle body.
14 Unscrew the four securing bolts, and withdraw the throttle body from the inlet manifold. Recover the gasket.
