Cleaning cost of Shen Feng ax7 throttle valve

The cost of cleaning the accelerator of Shen Feng ax7 is generally around 60 to 80 yuan, so it can be cleaned directly in the repair shop. There is no strict limit on the frequency of cleaning the throttle, which has a lot to do with car habits and environment. If it is dirty, it should be washed. Phenomenologically, cleaning should be considered when the idle speed is unstable. Under normal circumstances, the 4S shop will advise the owner to clean it once every 20,000 kilometers. Of course, the situation is different for different models. It is not uncommon for some cars to have dirty gas throttles and need to be cleaned after seven or eight thousand kilometers.

Three functions of regular cleaning:

1. It can effectively clean and dredge the glue and carbon deposit of the fuel nozzle and keep the fuel system clean.

2. It can clean the waste gas circulation system, reduce waste gas emission and save fuel, thus effectively protecting the oxygen sensor and the three-way catalytic conversion device.

3. It can help prevent symptoms such as knocking, unstable idle speed and poor acceleration caused by colloid and carbon deposition.
