Q: Car idling high when stopped

asked by on

My car idles high when in park or at a stop.

Hi there. A vehicle idling high can be caused by a couple of problems. First, it can be due to a loss of manifold pressure, causing the vehicle to compensate the lack of air intake by throttling higher on its own. Secondly, this may be caused by a faulty throttle position sensor. A certified mechanic, such as one from YourMechanic, can diagnose this issue more accurately in person.
