Wuling Light's new accelerator pedal, why is the accelerator still heavy? The accelerator is cleaned. Is it related to the fuel injector?

Did it appear before or after the line change? If it is changed, please pay attention to whether the line is adjusted tightly enough. If the air cabin is too dirty and the air intake is not smooth, there will be problems ~ the nozzle may be related ~ but the possibility is not high ~ the range cannot be reduced before measuring the cylinder pressure and oil pressure ~ the car will be weak because of the poor cylinder tightness, and the oil cannot be added too much ~ Check whether it is flushed ~ If all these are normal, it may be a new sensor ~ Oxygen sensors are common, and very few are caused by knock sensors.
