After cleaning the throttle, the fuel consumption increases. How to solve it?

After the negative electrode of the car battery is removed, put it back in a few minutes, and the RAM chip will be removed.

This is a very useful function, which can constantly repair the running state of the vehicle, but sometimes it often brings some trouble to the maintenance of the vehicle. For example, when it comes to the throttle, many vehicles find that the idle speed has become higher and the fuel consumption has increased after cleaning the throttle. In fact, it is because the vehicle after cleaning the throttle still runs according to the data of the original RAM chip.

In addition, once the car encounters a fault, the fault indicator light often lights up. Even if we fix the fault, the fault light will still light up, constantly reminding the owner that there is a fault. This is also a "haunted" RAM chip. At this time, if you want the vehicle to return to normal quickly, you need to clear the RAM data. Of course, in the garage, we can use special software to match vehicles through OBD interface.

The extended data RAM chip is used to store various variable data in automobile operation. The so-called variable data means that numerical data is variable and not fixed at any time. Such as throttle opening, system time, even audio parameters, seat adjustment parameters and so on. Like computer memory, once the power is cut off, the data in the RAM chip will be completely erased.

Moreover, once the parameters in the RAM chip are completely stored, the new data will occupy the oldest data and keep the freshness of the data in the chip. Therefore, cars have magical adaptive learning ability. For example, a car can automatically "remember" the driver's driving style and the state of the vehicle.
