What is the reason for the high fuel consumption after throttle cleaning?

After cleaning the throttle, the fuel consumption will increase obviously in a short time, because the original throttle has carbon deposit, and the fuel consumption will also increase after cleaning, which can be stabilized for a period of time or returned to normal through computer reset. The following information is introduced: 1. Reasons for the increase of carbon deposit after cleaning the throttle: the carbon deposit of the electronic throttle should be cleaned every 10000 km or after the fault indicator light is on. The removal of carbon deposit has a certain influence 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 will be more expensive. After the carbon deposit of automobile engine is removed, the driving computer needs a learning process to adapt to the running environment. This adaptation process is about 1000 km. 2, computer reset can reduce fuel consumption: generally, EFI vehicles need to do a computer reset operation after cleaning the throttle. 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. 1 min later, connect again and run the recovery again.
