>*Fuel Filter Clogged:* A clogged fuel filter can restrict the flow of fuel to the engine, causing the vehicle to stall. Check and replace the fuel filter as needed.
>*Fuel Pump Failure:* A failing fuel pump may not be able to deliver sufficient fuel to the engine, causing the vehicle to cut off. Have the fuel pump inspected to determine if it needs replacement.
>*Ignition Coil Issues:* Faulty ignition coils or spark plugs can lead to misfires and cause the engine to shut down while driving. Check the condition and replace any worn or damaged ignition coils or spark plugs.
>*Crankshaft Position Sensor (CPS) Failure:* A failing CPS can cause the engine to stall by interrupting the signals to the engine's ignition system. Check and replace the CPS as required.
>*Cam Position Sensor (CAM) Failure:* A faulty CAM sensor can cause engine stalling and other issues related to the engine's timing. Have the CAM sensor diagnosed and replace it if needed.
>*Air Flow Sensor (AFS) Malfunction:* A faulty AFS can provide incorrect air-to-fuel ratio data, leading to engine stalling. Have the AFS checked and replaced if necessary.
>*Battery Issues:* A weak battery or loose battery connections can cause electrical problems and disrupt the engine's performance, leading to stalling while driving. Ensure the battery is in good condition and its connections are secure.
>*Electrical Connection Problems:* Loose or corroded electrical connections can lead to intermittent electrical issues and engine stalling. Inspect and clean electrical connections (especially around the engine and battery) to ensure a good connection.
>*Vacuum Leak:* A vacuum leak can disrupt the engine's fuel mixture, leading to engine stalling. Check hoses, gaskets, and other components for leaks and repair or replace as necessary.
>*Throttle Body Problems:* A dirty throttle body or issues with the throttle position sensor can cause engine stalling. Clean the throttle body and inspect the throttle position sensor to ensure proper operation.
>*Computer Issues:* Problems with the vehicle's computer (Engine Control Module - ECM) can lead to engine stalling and other issues. Consult a professional to have the ECM diagnosed or repaired as required.
Note: It's important to have a qualified mechanic inspect and diagnose the specific issue causing the engine stalls in your 1997 Buick Le Sabre to ensure accurate repair and avoid potential safety risks.
