After replacing the spark plug to clean the throttle, the idle speed is normal, but the speed is high when refueling, and the speed can't get on the throttle. What are the reasons for not taking the initiative to upshift? First, in fact, whether the spark plug needs to be replaced, just take it down and check it to see the burning color, the gap between the electrodes, whether the gap between the porcelain body and the metal shell is leaking, and so on. If it is found that the car is difficult to start in cold state, there is obvious frustration and idling jitter when driving, or the acceleration performance of the engine decreases, the spark plug should be checked in time. Because once the vehicle shows the above performance, it may be caused by the aging of the spark plug.

Second, car maintenance is very troublesome. When the car travels to a certain number of kilometers, the spark plug will produce carbon deposit and the electrode gap will increase. Carbon deposition will increase the fuel consumption of the engine, and the increase of spark plug gap will lead to difficulties in starting. Therefore, regular inspection and maintenance of spark plugs can prolong engine life.

Third, keep:

1. Clean the air filter regularly to prevent dust from burning with mixed gas, which can prevent the spark plug from being corroded.

2. You can also remove the spark plug yourself to clean the dirt and carbon deposit on the ignition head. However, it is particularly important to note that when removing the spark plug, it should be noted that dust should not enter the cylinder when the spark plug enters and exits, and the surrounding area should be cleaned before removing the spark plug. If there is engine oil in the cylinder, the piston ring or other parts should be replaced in time to avoid electrode short circuit caused by carbon deposition in the spark plug.

3. In addition, the fuel is closely related to the life of the spark plug, so be sure to pay attention when refueling, and don't be greedy for cheap oil with poor quality, or you will regret it.
