Clean the throttle and fuel injectors.

In addition, the throttle and injector are generally cleaned once every 20,000 kilometers, otherwise the car will be difficult to start, the engine will shake, the fuel consumption will increase, and the idle speed will be unstable.

Throttle is what we usually call throttle, which mainly controls the air intake of the car. If it is not cleaned for a long time, it will cause carbon deposition. However, if the problem of carbon deposition is serious, it may lead to the car's throttle sinking, fuel not going or abnormal engine jitter. Pay attention to the cleanliness of the throttle when maintaining the car at ordinary times. If it is damaged, it must be replaced with a new one.

The injector mainly controls the injection of fuel, and it is also a place where carbon deposition is easy to occur. If the injector is not cleaned, it will also cause problems such as idle jitter and increased fuel consumption. Generally, the injector is cleaned every 20,000 kilometers.

When cleaning the throttle and injector, you can choose a repair shop or a 4s shop. The repair shop is cheap and quick to clean, but the quality is mixed. The cleaning quality of 4s shops is guaranteed, but the cost is high, and individual 4s shops will have a long waiting time.
