After the engine cleans up the carbon deposit, the fuel consumption becomes higher.

After the engine removes carbon deposits, the fuel consumption becomes higher. After cleaning the throttle valve, the fuel consumption will increase obviously in a short time, and it can be stabilized for a period of time or returned to normal after computer reset: 1, and the electronic throttle valve is cleaned once every 10000 km, or it can be cleaned after the fault indicator light is on. After removing the carbon deposit, it will have a certain impact on the performance of the car. Take the EFI car as an example. After cleaning up the carbon deposit in the oil circuit and throttle, the car should consume more fuel. After removing carbon deposits, the driving computer needs a learning process to adapt to the working environment of automobile engines. This adaptation process is about 1000 km. 2. Generally, after cleaning the throttle, the EFI vehicle needs to do computer reset operation. If you don't do it, it is likely to cause a big increase in fuel consumption. Generally speaking, the simplest reset method is to disconnect the battery cable for more than 30 seconds. I suggest you disconnect 1 minute and then connect again, and you should be fine if you run it again; 3. However, some models cannot be reset in this way, and they must be connected to the maintenance computer through the vehicle OBD interface. In this case, you can only go to the 4S shop or garage to repair the computer. @20 19
