BYD f3 changed the spark plug to clean the throttle, and then turned off the engine.

There are many reasons for the problem with this car. Suggested check: 1. Is the idle motor clean and working properly? 2. Whether the spark plug and cylinder pipeline are normal. 3. Whether the intake manifold pressure sensor works normally (when the water temperature reaches 80°c, its data value is 280-400). 4. Whether the throttle valve is in good condition. 5. Is the oil pressure of the oil pump enough?
