How to solve the problem of high fuel consumption and boredom when refueling?

1, the reason for this lack of power is that there is carbon deposit in the car for a long time, so it will be better to clean the throttle, and the spark plug and cylinder line will easily cause incomplete combustion, which will make the car weak.

2. Clean or replace the air filter element-throttle valve cleaning-fuel filter element replacement/cleaning-check the tightness of the cylinder-remove carbon deposit from the spark plug-clean the fuel nozzle-and ensure smooth exhaust.
