What is the reason for the car idling jitter after wading?

Idle jitter after wading may have the following reasons: 1, serious carbon deposition in the engine: the most common reason is that the throttle valve is too dirty or the nozzle has too much carbon deposition. 2, the ignition system problem: the ignition system is not easy to use, and the spark plug is not easy to use, which will also lead to this failure. 3. Aging of engine parts: The engine foot is actually the shock absorption system of the engine. The engine feet are responsible for absorbing the slight vibration of the engine during operation. If there is something wrong with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing idling jitter.
