Classic Focus's Solution for High Fuel Consumption

The first reason is the carbon deposit on the accelerator. Whether it is a turbocharged engine or a naturally aspirated engine, it is necessary to clean the throttle regularly. If it is not cleaned for a long time, there will be thick carbon deposit on the throttle, which will definitely affect the running state of the engine and cause idling jitter.

Solution: It is recommended to go to the 4S shop to clean the throttle.

The second reason is that the ignition performance of the spark plug decreases. Spark plug is an important part of engine. If the ignition performance of the spark plug decreases, it will affect the combustion of the engine, and insufficient combustion will lead to an increase in fuel consumption. Therefore, it is recommended to replace the spark plug regularly. The spark plug of the original Focus car can be replaced every 30 thousand kilometers or so.

Solution: you can replace the spark plug in the 4S shop;

The third reason is the serious carbon deposition in the engine. If the carbon deposit inside the engine is serious, it will affect the fuel consumption, and the impact is obvious. If the old car has the problem of high fuel consumption, it is recommended to clean up the carbon deposit inside the engine.

Solution: Go to the 4S shop to clean up the engine carbon deposit, and use the bottle hanging method;

The fourth reason is that the intake air flow sensor is faulty. Intake air flow sensor is an important component. If the signal transmitted to the engine is inaccurate, it will affect the fuel injection and eventually lead to an increase in fuel consumption.

Solution: this can only be replaced;

The fifth reason is that the oxygen sensor is faulty. The oxygen sensor will detect the oxygen content in the exhaust gas and feed back the signal to the driving computer. If the oxygen sensor data is inaccurate, it will directly affect the fuel injection of the engine, thus seriously affecting fuel consumption. When the oxygen sensor fails, the engine failure warning light will basically light up, so just check and replace it directly.

Solution: Replace the oxygen sensor before going to the 4S store. Million car purchase subsidy
