My car is the eighth generation Accord 2. 0 displacement is almost 30 thousand kilometers. I went to my friend's garage to clean the throttle during this maintenance. ...

This is a common problem of EFI engines. Signals from the engine electronic control center are provided by various sensors. I have driven tens of thousands of kilometers and have adaptive memory. If the valve is not cleaned, this phenomenon may not occur. Therefore, when driving in the future, remember that when the car is running smoothly, the maintenance should be done according to the regulations. If there is no obvious fault, it is best not to do things that should not be done. I've had the same experience. In the first half of the year, a tank of oil can travel 660 kilometers and carry out several long-distance transportation. In June, I began to clean the gas path and gas grid, and I felt that the fuel consumption increased. I really regret cleaning the airway. Another time was to maintain and change the oil, and the car collector publicized the oil additive and added one. When I came back, I felt that the engine was much louder and the idle speed was much higher than before. After a period of adaptation, the car slowly returned to its old appearance, and I regret that I shouldn't have listened to the salesman. You don't have to worry or do anything now. After a period of adaptation, I believe the car will recover slowly.
