Dear All,

(this is regarding my 1983 380SEC).
Should the air flow sensor (the big circular plate) be completely closed when the engine is idling?
I.e., is the idle control air flow valve able to supply all the air that is needed by the engine to idle?
If it is supposed to be closed, then the control piston in the fuel distributer rests at its bottom position (as the control pressure exceeds that of the air control valve's), right?

Your input is greatly apreciated.

Greg
