Important

During assembly the O-rings between the resonating chamber and throttle body may be incorrectly positioned with the result that the engine takes in air that has not passed through the mass air flow sensor. This could impair driveability with consequent fault diagnosis measures.

When any work is done that involves removing the resonating chamber from the throttle body, the following steps must always be taken:

• Check the condition of the O-rings and that they are properly seated.

Replace any O-rings that are deformed.

• Grease the O-rings with non-acidic petroleum jelly (vaseline).
