Best Answer

The idle is preset at factory. No adjustment provisions are provided. In cooler temperatures, it will take a little longer for the idle to come down. If the vehicle continues to have a higher than normal idle, then you will need to take it to a shop where they can diagnose the problem. Driving around with a higher than normal idle can damage the transmission.
