How often does the eighth generation Camry clean the throttle?

The throttle of Pacific Auto Network does not need to be cleaned regularly, because many high-speed cars are not dirty at all, and low-speed driving in urban areas often leads to excessive carbon deposition. To sum up, the throttle can be checked and cleaned, and it is not necessary to clean the nozzle under normal circumstances. If the engine is not in good working condition, you can try to clean it.

Carbon deposition in throttle and nozzle is generally related to improper use or inferior fuel of vehicles, not only Camry, but also many vehicles. Failure to clean for a long time will lead to the difficulty of cold start, engine jitter, too much black carbon deposition on the throttle, which will cause the throttle shaft to be stuck, the throttle is unstable, the nozzle is blocked, the atomization is poor, the mixture is difficult to burn normally, and the exhaust gas has a strong gasoline smell. So how long will it take to clean these two places? Let's say it according to the actual situation. The accelerator doesn't need to be cleaned regularly, because many cars driving at high speed are not dirty at all, and there is often too much carbon accumulation when driving at low speed in urban areas. For example, a customer's Peugeot 408 belongs to the kind that drives faster. It's been three years. It is said that the throttle of this car is difficult to remove and can't be seen inside the engine. It takes half a day to remove the screws by hand. Therefore, there is no carbon deposit in the throttle. So you can't clean the throttle according to the specified mileage and time. You can check it, remove the intake bellows, see if it is dirty and black, and then decide whether to clean it. So when will it be checked? You can check it every time you go for maintenance, especially for cars that often drive at low speed in urban areas. Stop-and-go traffic lights will lead to excessive carbon deposition. But don't be fooled, especially when a mechanic tells you that the throttle needs cleaning after driving 20 thousand kilometers. At this time, you can ask him to take apart the bellows and show it to you. If it is dirty, wash it. If it is not dirty, it is not necessary. Then let's talk about the fuel nozzle. Generally, the nozzle is rarely cleaned, but it is usually necessary to pay attention to the regular place to refuel. Inferior fuel may cause choke blockage, so the fuel filter should be replaced regularly. Generally, it is about 20,000 kilometers outside and 50,000 kilometers inside.

There are two ways to clean the fuel injector. One method is to "hang the bottle", remove the oil inlet pipe, connect the bottle connector of special equipment, cut off the power supply of the oil pump, and let the bottle cleaning liquid replace the fuel to clean the engine nozzle. The other is fuel addition, that is, before adding fuel, a bottle of cleaning agent is added to the fuel tank and the fuel nozzle is cleaned with fuel. So is cleaning useful? The actual effect of cleaning is less than the salesperson said. In the case of regular gas station refueling, the car is used normally, and there is no need to clean the refueling nozzle. If your car is in poor condition, wobbly and unable to accelerate, then you can try to separate the throttle, nozzle and spark plug. To sum up, the throttle can be checked and cleaned, and it is not necessary to clean the nozzle under normal circumstances. If the engine is not in good working condition, you can try to clean it.
