What is the idling jitter in Lang Wei (Buick Lang Wei engine jitter)?

What's the matter with Willard Idle Jitter (Buick Willard Engine Jitter) What's the matter with Willard Idle Jitter (Buick Willard Engine Jitter) Lang Wei Idle Jitter is probably caused by excessive carbon deposition in the oil circuit. Suggest cleaning the throttle or something. It is best to go to a professional maintenance station for further inspection and maintenance. The throttle valve is a metal plate in a circular tube, and carbon deposits are attached to the metal plate, which makes the metal plate thicker, so that air can not enter and exit smoothly, and even the throttle valve can not be closed. This leads to problems such as weak acceleration and engine jitter. However, carbon deposition is a slow accumulation process, and there will be no direct serious failure, so as long as the owner pays more attention to the condition of the vehicle during normal use, it is good to repair the problem in time. In addition, engines are now divided into naturally aspirated engines and turbocharged engines. For naturally aspirated engines, we usually add mineral oil or semi-synthetic engine oil, and we don't need to use all synthetic engine oil. But if the engine is turbocharged, it is necessary to add synthetic engine oil, because only in this way can we give full play to the thermal effect of the engine and give full play to the best working and lubricating effect of the engine oil. Only in this way can the engine achieve the best working condition and give full play to the dynamic effect. @20 19
