2022 Lu Zun knocked on the key and went out. What happened?

1, too much carbon deposit in the throttle valve leads to insufficient throttle opening; 2. The aging of spark plug leads to weak ignition energy; 3, the nozzle is blocked, resulting in less fuel injection; 4, engine or car computer short circuit power failure; 5. The oil used is unqualified; 6, the oil circuit is not smooth; 7. The wire plug is in poor contact; 8. The oil pressure of the oil pump is too low. The solution of flameout after ignition is: 1. Turn on the inching switch of the car, observe whether the indication of the gasoline meter is normal, and check whether there is oil in the fuel tank; 2. Check whether the circuit is faulty; 3. Observe whether the connecting wire between the starter and the battery is connected reliably.
