What should I do if the fuel consumption becomes higher after cleaning the throttle?

Causes and solutions of high automobile fuel consumption;

1, high fuel consumption of automobiles: tires. It is convenient to check the tires, so check the tires first. If the tire pressure is insufficient, the fuel consumption will increase. If there is nothing wrong with the air pressure, then check the degree of tire wear. When tires are seriously worn, there are often signs of slipping, which increases fuel consumption.

2, the car fuel consumption is high reason 2: engine. If the engine deposits more carbon in a short time, it will also cause higher fuel consumption. This situation is likely to be the use of substandard oil. The solution is to add a certain amount of detergent when refueling. If the effect is not obvious, it means that the engine has more carbon deposits. This situation must be handed over to a 4S shop or repair shop, and technicians will clean up the carbon deposits in the engine.

3. The reason of high fuel consumption of automobiles: oxygen sensor. As the internal control unit of automobile, oxygen sensor mainly monitors the oil-gas ratio of engine. Once damaged, it will cause the imbalance of engine oil-gas ratio, and the fuel consumption will inevitably increase abnormally. When the vehicle is driving, the exhaust pipe will emit dark exhaust gas. Replace the oxygen sensor as soon as possible.

4. Reason 4: A control unit of the engine. Although the electronic control unit of the engine is highly reliable, it is inevitable that those cars with long service life will fail. If one of the control units fails, it is likely to increase fuel consumption, accompanied by poor power performance and thick black exhaust.
