The fuel consumption is serious, and the throttle valve has not changed after cleaning and replacing the spark plug. What should I do?

When the fuel consumption of a car is serious, the owner cleaned the throttle and replaced the spark plug, and the fuel consumption of the car remains high. In this case, the car owner needs to remove the carbon deposit inside the car engine and clean the oxygen sensor of the car, because the fuel consumption of the car is not only the problem of the throttle and spark plug, but also the problem of the car engine and oxygen sensor.

First, remove the carbon deposit inside the engine.

You should know that the engine is the core of the car. Without the engine doing work, the car cannot run normally. When the car is driving for a long time, the driver's bad driving behavior and the use of inferior gasoline will lead to carbon deposition in the engine. After using inferior gasoline, the combustion chamber in the engine is not fully burned, which will lead to some mixed gas remaining in the crankcase. In the long run, this mixture will form carbon deposits, so this will cause carbon deposits in the engine. The automobile mainly wants to reduce the fuel consumption of the automobile, so it is necessary to remove the carbon deposit in the engine, because the carbon deposit in the engine is the most important reason that affects the fuel consumption of the automobile. Second, clean the oxygen sensor of the car.

The oxygen sensor is also one of the most important parts of the automobile, because it controls the oxygen composition required by the engine. If the car's oxygen sensor fails, it will send some wrong data to the trip computer. The trip computer mistakenly thinks that the weak engine power is due to the low fuel injection, so it will send data to the fuel injector to increase fuel consumption, which will directly lead to the increase of car fuel consumption. Third, summary.

Generally speaking, the fuel consumption of a car is the most concerned issue for many car owners, because the higher the fuel consumption of a car, the higher the use cost of the car owner. But for some cars with high fuel consumption, replacing the spark plug and cleaning the throttle have no substantial effect. At this time, the main focus of waiting is to clean up the carbon deposit inside the engine and clean the oxygen sensor of the car.
