如果发动机怠速达到正常的工作温度后，仍然抖动，那就属于故障了，怠速如果车身抖动明显，
济南奥迪汽车维修厂家认为可能意味着车辆存在下面4种状况：
If the engine still shakes after the idle speed reaches the normal operating temperature, it is a fault. If the body shakes obviously at idle speed, the Jinan Audi auto repair manufacturer believes that it may mean that the vehicle has the following four conditions:
1、发动机积碳严重
1. The engine has serious carbon deposition
车辆长时间行驶后，发动机或多或少会产生积碳，积碳主要附着于进排气门、发动机缸体、喷油嘴、节气门等位置，如果积碳过多，会显著影响发动机缸内燃油喷射量、空气进入量，进而影响发动机缸内燃油空气混合比，使发动机出现怠速抖动现象。
After the vehicle has been driving for a long time, the engine will produce more or less carbon deposits, which are mainly attached to the intake and exhaust valves, engine block, fuel injection nozzle, throttle valve and other positions. If the carbon deposits are too much, it will significantly affect the amount of fuel injection and air intake in the engine cylinder, and then affect the fuel-air mixture ratio in the engine cylinder, causing the engine to shake at idle speed.
2、发动机部件老化
2. Aging of engine components
发动机悬置(机脚垫)位于车身和发动机之间，是汽车发动机避震系统的一部分，负责吸收发动机在运转时候的细微抖动。如果悬置出现问题，其自身的滤震效果便会降低，造成怠速时车身发生抖动。这种抖动通常发生在发动机负荷发生变化的时候，比如踩下刹车挂D档、开空调、开大灯等。
The engine mount (foot pad) is located between the vehicle body and the engine. It is a part of the shock absorption system of the vehicle engine and is responsible for absorbing the slight vibration of the engine during operation. If there is a problem with the suspension, its vibration filtering effect will be reduced, causing the body to shake at idle speed. This jitter usually occurs when the engine load changes, such as pressing the brake to shift to D gear, turning on the air conditioner, and turning on the headlights.
3、点火系统问题
3. Ignition system problem
点火系统中某个缸不点火，或者点火弱也会导致怠速抖动，怠速不稳的问题。这里火花塞点火线圈都要检查，火花塞是否存在电机烧蚀损坏，间隙过大等问题，点火线圈是否有漏电，电压低，损坏类问题。另外还要注意点火时间是否正确，点火时间不对会出现爆震、发动机无力等问题，一样会导致发动机运行不稳，抖动。
If a cylinder in the ignition system does not ignite, or the ignition is weak, it will also cause idle jitter and unstable idle speed. Here, the spark plug ignition coil should be checked to see whether the spark plug has problems such as motor ablation damage, excessive gap, and whether the ignition coil has leakage, low voltage, and damage. In addition, pay attention to whether the ignition time is correct. If the ignition time is not correct, knock, engine weakness and other problems will occur, which will also lead to unstable engine operation and jitter.
4、油压不稳
4. Unstable oil pressure
造成发动机油压不稳的因素很多，例如机油缺少、机油脏污、机油变稀、机油油管漏油、机油泵损坏或其零部件磨损超标等等。值得一提的是，如果发动机持续在机油压力过低的条件下运转，情况严重时可能会造成发动机“烧瓦”，此时发动机将不能启动，需进行刮瓦或换瓦。
There are many factors that cause the instability of engine oil pressure, such as lack of oil, oil dirt, oil thinning, oil pipe leakage, oil pump damage or excessive wear of its parts, etc. It is worth mentioning that if the engine continues to operate under the condition of low oil pressure, it may cause the engine to "burn out" when the situation is serious. At this time, the engine will not be able to start, and it needs to be scraped or replaced.
怠速抖动具体怎么解决？
How to solve idle jitter?
1.原地怠速车身抖动，这个需要更换发动机机脚胶。
1. The vehicle body shakes at idle speed in place, which requires replacing the engine foot glue.
2.低速高档急加速时车身抖动，检查火花塞。
2. Check the spark plug when the body shakes at low speed and high speed during rapid acceleration.
3.开空调时刹车抖动，更换电子风扇。
3. The brake shakes when the air conditioner is turned on. Replace the electronic fan.
4.高速踩刹车方向盘抖动，更换前轮刹车盘。
4. Press the brake at high speed and the steering wheel shakes. Replace the front wheel brake disc.
5.高速踩刹车制动踏板抖动，更换后轮刹车盘。
5. Press the brake pedal at high speed to shake, and replace the rear wheel brake disc.
6. The steering wheel shakes when running at high speed, and the two front wheels need to be dynamically balanced. For more matters related to vehicle maintenance, please visit our website http://www.lutongqixiu.com Ask!
