Q: Car will not stay on after starting it sometimes

My car has an automatic transmission.

Hello, I'm curious if there are any problem codes set (they may or may not cause the Check Engine light to illuminate). If so, these will be helpful. Most auto parts stores will read these for you for free. I would check the idle control valve - may need to be cleaned or replaced. A leaking or open EGR valve will also cause poor low speed running and stalls. I would recommend having you car's stalling condition inspected completed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
