[RobertAnn]

The reasons why the car stalls when braking at a red light are: 1. Inexperienced driving skills or improper operation; 2. Fuel pump stuck or malfunctioning, causing poor fuel supply; 3. Use of low-quality fuel leading to excessive engine carbon buildup; 4. Faulty spark plugs or ignition coils, resulting in multiple cylinders not firing; 5. Excessive dirt on the idle motor valve core and throttle body. The solutions for a car stalling when braking at a red light are: 1. Quickly break in the car and improve driving skills; 2. Use qualified fuel; 3. Clean the fuel system, injectors, and fuel tank; 4. Clean the throttle body; 5. Clean the idle motor; 6. Replace the engine oil and oil filter.
