What is the reason for Buick Hideo's idling jitter? What is the reason for Buick Hideo's idling jitter? The general reason of Yinglang idling jitter is that the throttle is too dirty or the injector has too much carbon deposit. In addition, check the working conditions of spark plugs, high-voltage lines and ignition coils. Poor ignition system and poor spark plug misfire can also lead to such failures. The following is an introduction about the reason why Yinglang's idling vibration is particularly large: 1. The throttle valve is too dirty or damaged, which affects the idle vibration. You can clean the throttle first, and if the fault still exists, you need to replace the throttle assembly. 2. The spark plug doesn't work, which affects cylinder loss and idle vibration. You can check whether the spark plug and ignition module are faulty. 3. The rubber parts inside the engine and transmission bracket are aged and cracked. If the engine can't absorb the vibration when working, the problem of idle vibration will occur. The causes of idling jitter include serious carbon deposition in the engine, problems in the ignition system, unstable oil pressure, aging engine components, etc. If idling jitter occurs, the owner is advised to clean the engine, replace the spark plug and check the fuel supply pressure. @20 19
