Separating the Airflow meter
You then should separate the airflow meter from the main loom by disconnecting the wiring plug
There is a little yellow clip on the side of the plug push this up & squeeze the sides of the plug together & it should pull free.
Then remove the 2 10mm bolts that hold the airflow meter to the airbox(one at the front & one on the back)
Underneath the car you will see 2 prongs moulded onto the airbox these just pop out. Unsrew the jubilee clip that links the airflow meter to the hose from the inlet manifold. Once you have done this the airbox should pull free. Be very carefull not to drop the airflow meter as it will break easily & is an expensive part.
