Abstract
In a fuel control method data used to control the amount of the fuel supply in the previous cycle is corrected in response to the output of an O.sub.2 sensor in a current cycle, and added to or subtracted from the corrected data value as the difference between a value derived from data stored in a map based on the output of a vacuum sensor and engine rotation speed in the previous cycle and a value derived from the data stored in the map based on the output of the vacuum sensor and engine rotation speed in the current cycle. The sum or difference is used as current control data.
