Q: Car shutting off at stop light , 2002 Nissan

asked by on

Everytime I come to stop at a red light my car shuts off. It's fine while I'm driving but when I'm stopoed it feels like it's shaking & just shuts off. The stereo lights & everything stays on but the engine is off

My car has 120 miles.
My car has an automatic transmission.

This may be a sign of a failing idle air control valve. The idle air control valve is located on or near your intake manifold and monitors the air intake as it is mixed with fuel prior to being injected into the engine. This valve is controlled by the vehicle’s computer which 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. In cases where this valve is clogged or failing, your vehicle will stall instead of slowing to an idle after the release of the throttle. I would recommend having an expert from YourMechanic come to your home to replace your idle air control valve.
