Hello. There are several possible issues that could cause this problem: a dirty or malfunctioning idle air control valve, throttle body, stuck open (even partially) EGR valve, or an air leak in the intake system. I would recommend having a inspection to determine why the car is stalling completed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment for repairs.
