As the core component of a car, the importance of the spark plug is self-evident. Spark plugs also have a certain service life and need to be replaced in time. When the spark plug needs to be replaced, the car has three major characteristics:
1. It is difficult to start. There is too much carbon deposit on the spark plug, or too much precipitate material has accumulated, the spark plug gap increases, and the ignition energy is insufficient, making the car difficult to start.
Second, there is insufficient power, especially when climbing. It takes a long time to increase the speed when stepping on the accelerator!
3. Idle jitter. The car will shake irregularly while idling. In serious cases, there will be a flameout phenomenon!
At first, the car was difficult to start. It would take a long time to press the car to start, or it would take several times to start it successfully. At one time, it was suspected that the one-button start button was broken. Some people said that the key might have run out of power, so they quickly replaced the battery, but it did not work. After asking the mechanic who repaired the car, I realized that the spark plug might need to be replaced. According to the maintenance manual, the service life of more than 40,000 kilometers in three years has exceeded, so I quickly made an appointment to replace it.
There were still a lot of people in the store on weekends, and there was a long line.
After waiting for half an hour, it was finally our turn. Find a workstation and park it in.

First, use a special tool to remove the ignition coil. This requires a special tool. If you pry it hard, it can be easily pried out.
Although the ignition coil is not big, don’t remove it casually. It is still very dangerous if it is electrified!
Using a socket wrench to remove the spark plugs one by one may seem simple, but if you remove them yourself, it will be very difficult even with a wrench. Therefore, professional things are left to professional people!
The old spark plug looks very black, and the distance between the two electrodes is already a bit large. This will cause a small spark when igniting, which will make it difficult to start and lack of power when accelerating!
Replace the new spark plug, first put the spark plug in with a socket wrench, and then tighten it with a wrench.
