How to deal with the unstable idle speed of the throttle after washing?

1, check the oil level. Unstable idle speed of diesel engine throttle is usually caused by low oil level. Professionals should be invited to check the oil level to ensure that the oil white series is normal. 2. Check the throttle model. Throttle will be affected by air pollutants during use. Therefore, check whether the throttle model is consistent with the model and confirm whether the air in the throttle piston circuit is smooth.

3. Check the valve adjustment screw, and check whether the throttle idle adjustment screw is loose and over-adjusted. If so, it should be tightened.

4. Check the fuel injector and oil cooler. The diesel engine has great engine pressure. If the fuel injector and oil cooler don't work, it may affect the oil flow, thus affecting the idling performance of the throttle.
