Q: Car idles low. What's going on?

asked by on

Car idles low when come to a stop. It acts as if it wants to cut off

My car has 123000 miles.
My car has an automatic transmission.

Hey there. The engine will need to be checked for vacuum leaks in the PCV system or if the Check Engine Light is on and the idle control valve stopped working. Have a mechanic scan the computer and test the idle control circuit along with any possible vacuum leaks in order to diagnose the idling problem.
