asked by on December 10, 2016

Car stalled in stop and go traffic, lost power steering and acceleration. Was able to move car to median placed car in park and turned off the key. Re cranked the car and it struggled to turn over but eventually did. Have not had trouble with it since.

My car has 160000 miles.
My car has an automatic transmission.

Idle Control Valve Replacement $146.15 - $920.51 Get a Quote

Your car may have a dirty or failing idle air control valve. The idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle. Since this valve is controlled by the vehicle’s computer, it will adjust idle speed based upon other measurements such as engine temperature, intake air temperature and electrical system load or voltage. When you accelerate, the engine RPM increases, and as you let off the gas, the RPM slowly returns to the normal idling speed with the help of the idle air control valve making the transition from a higher RPM back down to idle speed. When the engine RPM drops below the normal range of about ~800 RPM, this often times will cause the engine to stall indicating a dirty or faulty idle air control valve. I would recommend having an expert from YourMechanic come to your location to diagnose and replace your idle air control valve.
