Engine stalls after start up, low idle

I'm Dusty, one of the auto experts on RepairPal's Car Genius team. I'm here to help! If your vehicle stalls after startup, it could happen for several reasons. The OBD code P0506 indicates that the engine idle speed is lower than the powertrain control module expects, but the exact cause is still uncertain. Issues with the fuel system, such as a failing fuel pump or a clogged fuel filter, may be the culprits. Low idle speed could also result from a dirty or malfunctioning idle air control (IAC) valve, throttle body, or an intake vacuum leak. You can try cleaning the throttle body and IAC valve, which might resolve the problem. Sometimes, carbon build-up can restrict airflow or throttle plate movement, impacting the idle speed. If these steps don't fix the issue, it's best to consult a professional technician. They have more advanced diagnostic tools and expertise to pinpoint the exact cause and get you on the right track to resolving the stalling problem.
