Frustration in the driving of Qingling Isuzu 4.2m van.

1, engine power supply system: spark plug, ignition coil, if the high voltage flashover is not good, the engine will work intermittently;

2. Oil supply system: injector, if the injector has carbon deposit, or is slightly blocked, or the atomization is not good, it is easy to cause abnormal oil injection;

3. The gearbox is impacted, frustrated and blocked, generally the valve body is damaged, or the gearbox oil is dirty, and there are impurities in it, especially the dirty impurities in the valve body gather and block the pipeline, which leads to the failure to effectively adjust the oil pressure, resulting in frustration, impact skidding and other problems;

4. The engine foot pad is damaged, and the gearbox foot pad is damaged. Loosening the throttle will not play a buffering role, which will produce a sense of frustration;

5, the throttle is not cleaned for a long time, and there is too much carbon deposition, which leads to the change of throttle opening angle, and there will be a sense of frustration when the throttle is released.
