Q: Idle problems with car.

asked by on

My car is idling high. What can cause that?

A: This problem of idling high is most likely ...

This problem of idling high is most likely a problem with the idle air control valve stuck or a vacuum leak in the intake system of the engine. I would recommend having your high idle speed inspected by a mechanic, the computer system should also be checked for codes and the engine intake checked for leaking vacuum hoses by a qualified technician.
