Abstract
A method of an electronic engine control for an internal combustion engine having a plurality of cylinders, wherein the very same air fuel ratio feed back coefficient obtained at a predetermined sequential timing which has been used for calculating the amount of fuel to be injected to a specific cylinder is also used for correcting timing of ignition for the same cylinder which follows immediately after the calculated amount of fuel has been injected into the specific cylinder, thereby the engine torque fluctuation is effectively suppressed, stability of engine operation during idling operation is improved and the surge during a low speed running is prevented.
