Is it normal to increase fuel consumption after cleaning the throttle?

After washing, the fuel injection diameter of the injector increases, and the fuel ejected per unit time increases, so the increase in fuel consumption is normal. The following are specific ways to reduce fuel consumption: 1. Step on the gas pedal lightly: the car is at the peak of fuel consumption when starting at a low speed, so step on the gas pedal lightly when starting to prevent speeding and effectively reduce fuel consumption. 2, avoid high speed: try to avoid unnecessary high speed, engine speed up and down will also greatly consume fuel. 3. Regular maintenance: change the oil regularly to remove carbon deposits. 4. Avoid emergency braking: predicting road conditions in advance and avoiding emergency braking can not only improve driving safety, but also save fuel, such as slowing down before traffic lights and using inertia to slide.
