Abstract
On start of an engine, a difference ΔPm between a first intake pipe pressure Pmand a second intake pipe pressure Pmis computed. Reduction correction of wall surface deposition correction is prohibited until the state that the difference ΔPm is equal to or less than a reference value ΔPmref continues over a predetermined number of strokes nref of the engine.
