After cleaning the accelerator, the car became easier to drive.

Under normal circumstances, as long as the replacement spark plug is of the same model and calorific value, it will not affect the power. However, if the replacement spark plug is different from the original requirements, it will usually affect the combustion effect and may lead to power reduction.

There is a time limit for cleaning the throttle, which does not mean that the throttle should be cleaned every time the car is serviced. This will have a negative impact on the car and increase the service time of the throttle. Then the correct cleaning mileage is generally 30,000 kilometers at a time, which not only ensures the good work of the engine, but also ensures the original power and reduces the fuel consumption of the car.

Generally speaking, for engines with high compression ratio and high power:

Due to the high temperature in the engine cylinder, the cold spark plug with high calorific value should be matched to avoid the spark plug heating up too fast, while the hot spark plug with low calorific value is usually selected for engines with low power, small displacement and low compression ratio to avoid the low temperature and difficult ignition caused by the rapid heat dissipation of the spark plug. Therefore, improper selection of spark plug calorific value will affect the ignition efficiency of combustion chamber, and even lead to serious carbon deposition in engine cylinder.

After cleaning the throttle valve, put it back in its original position. If there is no matching and relearning after assembly, the vehicle may have problems such as unstable idle speed and weak acceleration. Remember to re-learn to match the throttle valve with the automobile fault decoder to ensure that the throttle valve data is correct and the vehicle can run normally.
