Summary:A method of air/fuel ratio control for a multicylinder internal combustion engine, utilziing an oxygen concentration sensor which produces an output varying in proportion to oxygen concentration, in which compensation values are computed and stored for use in compensating errors of a basic value which controls the air/fuel ratio. While the engine is operating in a condition condition in which the deviation of a detected air/fuel ratio from a target air/fuel ratio is below a predetermined level, respective compensation values are computed and updated for the individual cylinders of the engine, with these compensation values being computed in accordance with variations in the magnitude of the detected air/fuel ratio.
