What happened to the weight of Delong f3000 accelerator pedal?

In this case, the accelerator cable needs to be replaced, the inside has rusted, and sometimes the pedal itself will get stuck. You'd better go to the repair shop for inspection.

Generally, there are two structures. Usually, the cable accelerator pedal is connected to the throttle through a cable. If the accelerator pedal sinks, try turning the throttle to see if it doesn't stick. If it doesn't hairpin, put some oil in the accelerator cable. There is also an electronic throttle. Check whether there is a hairpin on the pedal.
