engine stalls at idle and then can be restarted

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! When your engine stalls at idle but starts right back up, it’s like dealing with a finicky cat—you never know when it’ll decide to act up! Since you’ve had parts replaced, the problem might be with something that affects idle control, like the idle air control valve or throttle body. These parts help regulate airflow when the engine is idling. If they’re dirty or malfunctioning, they can cause random stalling. It’s also worth checking for vacuum leaks, as even a tiny one can disrupt idle stability. Since you mentioned the problem started after the engine replacement, double-check all the connections and grounds from that job. Sometimes, the little things can be the culprits! If you have any other questions, please call us at 877-913-1554! We'll gladly find you a certified RepairPal shop in your area!
