Some Buick Regal owners report experiencing engine stalling when coming to a stop or during low-speed driving, even after multiple repairs. Common causes identified include issues with the fuel system, air intake system, or ignition system, which can lead to stalling problems. Additionally, an erroneous signal from the MAF sensor may trigger the check engine light and diagnostic trouble codes, contributing to the stalling. Engine timing issues, particularly with Variable Valve Timing (VVT), and intermittent power connections or ignition system problems, such as faulty ignition switches, have also been reported as contributing factors. Owners are advised to check for specific error codes using diagnostic tools and to investigate potential issues with the fuel, air intake, ignition systems, and engine timing. Ensuring proper electrical connections can help prevent stalling during low-speed driving. For those facing ongoing stalling issues, consulting a qualified mechanic for thorough diagnostics and targeted repairs is essential for resolution.
