What Causes a Buick Regal to Suddenly Stall While Driving?

[EleanorLynn]

Buick Regal suddenly stalls while driving for the following reasons: 1. Use of inferior fuel: The use of low-quality fuel leads to engine carbon buildup and stalling. 2. Engine computer failure: Once the engine computer fails, it can cause the car to stall, which is a control issue. 3. Insufficient driving skills: The driver's lack of proficiency or improper operation can also cause the car to stall. 4. Simultaneous multi-cylinder failure: It may be due to spark plug or ignition coil failure, causing one or more cylinders to misfire, leading to stalling. However, only simultaneous multi-cylinder failure can cause stalling, so this possibility exists but is not very high. 5. Engine self-failure: Damage to the engine idle control valve or its circuit, or issues with the idle control module in the engine's electronic control unit. The likelihood of engine self-failure is extremely high among the many causes of car stalling. 6. Fuel pump failure: A stuck fuel pump or the fuel pump itself failing can cause sudden fuel cutoff, which easily leads to car stalling.
