Abstract
A feedback control of an air-fuel ratio of an internal combustion engine is performed in such a manner that when fuel injection is resumed from a condition where fuel injection is stopped due to deceleration running, air-fuel ratio feedback control is resumed once the output from an air-fuel ratio sensor indicates an air-fuel ratio less than or equal to a threshold value SL.
