In a fuel amount control apparatus arranged to determine the amount of fuel to be fed to respective cylinders so that the scattering in torque generation throughout the cylinders is suppressed, the amount of correction which is either added to or subtracted from a basic fuel amount, is computed such that a sum total of fuel amount correction factors substantially equals zero. To this end the sum total of the correction factors is first computed and is then checked whether an absolute value of the sum total is greater than a predetermined value. When greater, a given amount is either added to or subtracted from correction factors respectively provided for respective cylinders.
