Stalling in a Buick Regal with a 3.1-liter engine can be caused by several factors, including fuel delivery issues, such as a clogged fuel filter or failing fuel pump, which can restrict fuel flow. Additionally, problems with the ignition system, like worn spark plugs or a faulty ignition coil, can prevent the engine from maintaining proper combustion. Vacuum leaks or malfunctioning sensors, such as the mass airflow or throttle position sensors, can also lead to stalling by disrupting the air-fuel mixture. Regular maintenance and diagnostic checks can help identify and resolve these issues.
