How to distinguish the fault of throttle?

If the throttle valve of automobile engine is not flexible to open and close, it can not guarantee to provide the engine with the quantitative mixture needed for actual operation, and the pedal linkage mechanism is loose, which is the poor opening and closing of the throttle valve. \x0d\ The reason why the accelerator pedal linkage mechanism is loose is that the length of the soft steel wire rope that affects the opening and closing of the accelerator door is not properly adjusted. When you step 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, and so on. Most of them are caused by insufficient tension of wire rope. \ x0d \ x0d \ Troubleshooting: \x0d\ 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 throttle valve caused by the wire rope. \x0d\2。 If the bending 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. \x0d\ 3。 Another inspection method is to step on the accelerator pedal to see if the throttle can stand upright, that is, fully open, to judge the fault.
