Airflow meter - removal and refitting
Note: A tachometer and an exhaust gas analyser will be required to check the idle mixture on completion.
1 Disconnect the battery negative lead.
2 Depress the locking clip on the airflow meter wiring plug and disconnect the plug.
Pull on the plug, not the wiring.
3 Loosen the securing clip and disconnect the air inlet hose from the airflow meter.
4 Release the four securing clips and lift off the air cleaner lid with the airflow meter.
5 Remove the four securing bolts and separate the airflow meter from the air cleaner lid (see illustration). Recover the seal.
