The accelerator and clutch of the truck froze in the morning. How did this happen?

Air filter is blocked; The air inlet sensor is invalid or damaged; The syringe is too dirty; Injection pressure regulating valve pressure is not enough.

Check whether the throttle valve has carbon deposit; The inspection items such as the car can't start, the idle speed is unstable, the speed is high and low, and the oil supply is abnormal are as follows:

1, automobile battery voltage is low; Specific detection method: test the battery voltage with a voltage range of three meters. If it is lower than 10V, it is recommended to replace it. If it is around 1 1V, it is barely used; Be prepared to be replaced. 12V or more;

2. Check whether it is caused by carbon deposition; If driving about 20,000 KM, check and clean the throttle;

3. Check, test and replace the spark plug;

4. Confirm the oil quality of the added gasoline;

5. Check the ignition switch;

6. Test and check the starter, gasoline pump, sensor and other related parts of the starting and oil supply system.

Extended data:

The introduction of automobile throttle line icing in winter is as follows:

What's the difference between idle speed of vehicles? The hazards of high idle speed are increasing fuel consumption, increasing engine working temperature and increasing machine wear. The hazard of low idle speed is that it is easy to turn off when starting. If you start it frequently, it will be bad for the engine and starter. In addition, if the idle speed is too low, it is very likely that the vehicle will turn off when driving, which is very dangerous. It is easy to accumulate carbon in the engine cylinder for a long time, which leads to weak acceleration.

There is an idle motor next to the throttle. Idle motor mainly adjusts the air flow in the bypass pipe or fully opens the throttle valve to control the air intake when the engine is idling, so as to control the idle speed.
