ABSTRACT:
A fuel supply of an internal combustion engine is controlled by sampling a vacuum level within an intake pipe of the engine and a value corresponding to the engine rotational speed at predetermined sampling intervals, subsequently correcting a latest sampled value P.sub.BAn of the vacuum level with a latest sampled value M.sub.en of the value corresponding to the engine rotational speed to produce a corrected value P.sub.BA, and then determining fuel supply amount in accordance with the corrected value P.sub.BA. By determining the fuel supply amount in this way, hunting of the engine rotational speed especially during idling operation of the engine is prevented.
