A method is described for controlling the fuel supply of an internal combustion engine having a throttle valve in an intake air system, comprising the steps of: detecting when an angular position of a crankshaft of the engine coincides with a predetermined crankshaft angular position; detecting a pressure in an intake air passage downstream of the throttle valve whenever the coincidence is detected; calculating a present reference value P/sub BAVEn/ having a predetermined functional relation to a present detection value P/sub BAn/ of the pressure in the intake air passage and a preceding reference value P/sub BAVE(n-1)/ calculated by a preceding step of calculating a reference value, and determining an amount of fuel supply into the engine on the basis of the present reference value P/sub BAVEn/.
