What caused the fault of Dongfeng Citroen c4l 1.6t throttle?

Reason: When stepping on the accelerator pedal, the engine speed can't go up, or the engine can't generate enough power without stepping on the accelerator pedal, which is mostly caused by insufficient tension of the steel wire rope. Solution: 1 Unscrew the fixing bolts and nuts of the air filter, open the filter cover and take out the filter, so that you can clearly see the opening and closing of the air valve driven by the steel wire rope. 2 If the bending amount of the wire rope is extremely small, it means that the wire rope is very tight. Even if the driver releases the accelerator pedal, the throttle cannot be completely closed, resulting in excessive fuel supply and extremely high waiting speed. In addition, there is an inspection method to judge the fault by stepping on the accelerator pedal and then seeing whether the throttle can be in the vertical position, that is, fully open.
