In fact, the price of ignition coil is not expensive. According to the vehicle brand premium and the product strength of ignition coil itself, the price is generally around 100-300 yuan.

点火线圈的更换方法：

Replacement method of ignition coil:

一、打开发动机舱盖，并将发动机罩卸下，此时我们便可看到各缸裸露的点火线圈。

1、 Open the engine compartment cover and remove the engine hood. At this time, we can see the exposed ignition coils of each cylinder.

二、将图中黄色插销慢慢向外提起(右)，注意切不要将插销提断;而后再向下压动黑色卡扣柄，并同时向外(右)慢慢拔出插头。由于每缸插头都与其对应的气缸一一对应，所以切勿搞混。

2、 Firstly, lift the Yellow bolt out slowly (right) in the figure, and pay attention not to lift the pin off; then press down the black buckle handle and pull out the plug outward (right) slowly at the same time. Since each cylinder plug corresponds to its corresponding cylinder, do not confuse it.

三、使用对应的套筒工具将各缸点火线圈的固定螺丝卸下，并将点火线圈拔出。

3、 Use the corresponding sleeve tool to remove the fixing screws of the ignition coil of each cylinder, and pull out the ignition coil.

四、将新的点火线圈一一装回点火线圈孔中，在装回去的同时，一定要保证其与火花塞端子稳定结合。

4、 Install the new ignition coil into the ignition coil hole one by one, and make sure that it is stably combined with the spark plug terminal.

五、使用固定螺栓将点火线圈固定牢靠，并插上各气缸对应的点火线圈插头，将插口插销向内推锁止位置。

5、 Fix the ignition coil firmly with the fixing bolt, plug in the ignition coil plug corresponding to each cylinder, and push the socket plug inward to the locking position.

六、发车测试点火线圈是否正常工作，如一切正常，将发动机罩装回发动机即可完成点火线圈的更换工作。

6、 Test whether the ignition coil works normally. If everything is normal, replace the ignition coil by installing the hood back into the engine.

点火线圈坏了是什么症状?

What symptom is ignition coil broken?

点火线圈坏了故障症状更明显的特征就是发动机缺缸，怠速状态下发动机可能会有明显的突突突声音，用手在排气管上感觉更明显，并且伴随的是发动机抖动厉害，那么就可以判断有可能是点火线圈坏了。

If the ignition coil is broken, the most obvious feature of the fault symptom is that the engine is lack of cylinder. The engine may have obvious popping sound at idle speed. It is most obvious to feel it on the exhaust pipe by hand, and accompanied by severe engine shaking, then it can be judged that the ignition coil is broken.

点火线圈坏了汽车行驶中，档位越高，加油的时候汽车的顿挫感越明显发动机抖动厉害，平顺给油稍微要好一些，猛油的情况下是更能体会的，甚于有要熄火的感觉。

The ignition coil is broken. When driving, the higher the gear is, the more obvious the bumping feeling of the car is when refueling. The engine vibrates violently. It is better to give the fuel smoothly. When the fuel is fierce, it is most obvious that the car will even turn off.
