How does Ford forest adjust the idle speed?

Hello, according to the problem you described and our vehicle maintenance experience, this car is an electronic throttle, and the idle speed cannot be set and adjusted. It is normal for a cold car to start at high idle speed in winter, as long as it does not exceed 1200 rpm. This is designed by the driving computer for engine preheating, and it will automatically drop to normal idle speed after hot driving. If the idle speed exceeds 1200 rpm or is unstable, it is generally normal. If there is something wrong with the car, ask the car master. 4S shop professional technician, 10 minutes to solve.
