Fast idling of an engine when it is cold typically indicates that the engine's cold start enrichment system is functioning, which allows for a richer fuel-air mixture to aid in starting and warming up the engine. This is common in carbureted engines or can be managed by the engine control unit in modern fuel-injected engines. If the engine continues to idle fast after warming up, it may suggest issues like a malfunctioning idle air control valve or vacuum leaks.
