Didn't Tianyi c5 call the police with an air filter?

Call the police. The engine is unresponsive, and the acceleration and deceleration are normal. This happens because the fuel quality is poor or the air filter is dirty, and the dirty throttle valve leads to insufficient air intake of the engine. Therefore, Tianyi c5 will call the police if it is not equipped with an air filter. As long as you go to a regular gas station to refuel, regular maintenance of the vehicle will prevent the occurrence of excessive exhaust gas.
