My car has an automatic transmission.
Your vehicle uses electronic throttle control to maintain the desired idle speed. In this system, the engine control module (ECM) receives input from various sensors to determine how much the throttle should be open. It then opens and closes the throttle by means of a throttle-mounted motor. A problem in this system could cause the issues you’re having. A vacuum leak is also a likely cause. The only way to know for certain is to have your high idle issue diagnosed firsthand by a professional. YourMechanic is an excellent option since we come to your home or office.
