Answer 1

The recommended RPM for a vehicle's fast idle generally ranges from 1000 to 1200 RPM, but cannot be precisely determined without specific information about the vehicle. Consult the owner's manual or a technician for the most accurate advice.

Step-by-step explanation:

If a vehicle is left running, the RPM setting for a fast idle typically varies depending on the make and model of the vehicle as well as the conditions under which it is operating. However, many automotive sources suggest that a general fast idle speed can be anywhere from 1000 RPM to 1200 RPM. Without specific details about the vehicle or conditions, it cannot be precisely determined. The vehicle's owner's manual or a professional technician should provide the most accurate recommendation for fast idle settings.
