Abstract
An engine has a fuel injection system and an idle regulating control valve. The idle regulating valve is initialized upon engine shut down by closing to a fully closed position such that a reference value can be obtained in such a position. Once fully closed, the idle regulating valve is opened to a predetermined position and a value is written into memory that indicates that the initialization procedure has been completed. During subsequent restart, if it appears that the initialization procedure has not been completed prior to attempted restart, fuel injection is temporarily suspended. The fuel injection can be suspended during a subsequent initialization, until the idle regulating valve is fully closed or for a predetermined period of time. In some less refined applications, the idle regulating valve can be initialized during engine start up regardless of whether or not it is initialized during engine shut-down.
