Why does the car stall immediately after starting?

[AngelaMarie]

The reasons for a car stalling immediately after starting are: 1. Stalling caused by carbon deposits: Carbon deposits can accumulate in the throttle valve, spark plugs, cylinders, fuel lines, intake passages, etc. These are a coking-like substance produced by fuel under high temperatures, which is difficult to remove physically and requires cleaning with a chemical cleaner; 2. Fuel quality and clogged fuel injectors: Using low-quality fuel can produce more carbon deposits, clogging the fuel injectors and resulting in poor atomization; 3. Ignition system issues: Severe carbon buildup on spark plugs and insufficient ignition voltage; 4. Power supply problems: The car battery is severely depleted, making it difficult for the engine to start.
