When the truck is idling, it will not shake when refueling.

The reasons and solutions of truck idling jitter and no jitter after oil supply are as follows:

1. The intake manifold is damaged and the intake manifold is poorly sealed. When the air supply system leaks, the intake signal obtained by the engine electronic control unit is inaccurate and the judgment is wrong, which leads to the engine idling instability.

Solution: Replace the new intake manifold to ensure the normal air supply and idle speed of the engine.

2. Too much carbon deposit on the valve and intake pipe.

Solution: Clean up the engine carbon deposit. Common carbon deposit cleaning includes carbon deposit cleaning of throttle, spark plug, injector and cylinder. Oil circulation cleaning, dry ice cleaning and walnut sand cleaning can all achieve certain results.

3. The sensor and other circuits that control the idle speed are out of order.

Solution: Measure the sensor and circuit, replace the damaged sensor, and ensure the normal idling of the engine.

4. Ignition system failure. When the spark plug has more carbon deposits or insufficient ignition voltage, it is easy to cause insufficient engine power and eventually lead to jitter.

Solution: It is recommended to go to the auto repair shop to clean the spark plug and carbon deposit on the oil road.

5. Engine internal parts are aging.

Solution: Replace the engine with a new one, or go to a 4s shop for maintenance.

6. The fuel pressure is unstable. When the fuel system leaks or is blocked, the fuel pressure will be unstable and the engine will shake intermittently.

Solution: You can go to the auto repair shop to conduct a comprehensive inspection of the vehicle fuel supply system and find out the reason for the jitter.

7. Piston deposits.

Solution: Clean or replace the air filter, fuel filter and oil filter as appropriate.

8. Nozzle deposits.

Solution: Replace the fuel injector with a new one. The new injector needs a computer, and it should be disassembled in order. Million car purchase subsidy
