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.

點火線圈的更換方法：

Replacement method of ignition coil:

一、打開發(fā)動機艙蓋，并將發(fā)動機罩卸下，此時我們便可看到各缸裸露的點火線圈。

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、首先將圖中黃色插銷慢慢向外提起(右)，注意切不要將插銷提斷;而后再向下壓動黑色卡扣柄，并同時向外(右)慢慢拔出插頭。由于每缸插頭都與其對應的氣缸一一對應，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、使用對應的套筒工具將各缸點火線圈的固定螺絲卸下，并將點火線圈拔出。

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、將新的點火線圈一一裝回點火線圈孔中，在裝回去的同時，一定要保證其與火花塞端子穩(wěn)定結合。

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、使用固定螺栓將點火線圈固定牢靠，并插上各氣缸對應的點火線圈插頭，將插口插銷向內推至鎖止位置。

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、發(fā)車測試點火線圈是否正常工作，如一切正常，將發(fā)動機罩裝回發(fā)動機即可完成點火線圈的更換工作。

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

點火線圈壞了是什么癥狀?

What symptom is ignition coil broken?

點火線圈壞了故障癥狀更明顯的特征就是發(fā)動機缺缸，怠速狀態(tài)下發(fā)動機可能會有明顯的突突突聲音，用手在排氣管上感覺更明顯，并且伴隨的是發(fā)動機抖動厲害，那么就可以判斷有可能是點火線圈壞了。

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.

點火線圈壞了汽車行駛中，檔位越高，加油的時候汽車的頓挫感越明顯發(fā)動機抖動厲害，平順給油稍微要好一些，猛油的情況下是更能體會的，甚至于有要熄火的感覺。

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.
