[QUOTE="mcatrophy, post: 1441231, member: 3187"] I would have thought cold idle is required because the engine is cold rather than the ambient air is cold. The latter is more for fine control of mixture to achieve low emissions, this wouldn't affect the requirement for fast idle when the engine is first started. The Gen 3 idle, hot and cold, is controlled directly by the ECU adjusting the throttle, rather than the hot wax mechanical gismo used by the Gen 2. Coolant temperature is the obvious place to check for engine temperature. [/QUOTE]
