What is the reason for no response when stepping on the accelerator and restarting to solve it?

It should be due to the electronic throttle. The onset period is more frequent in colder weather. Throttle failure is common now, as many cars use electronic throttles instead of the older cable-operated ones. The electronic throttle requires signals from the accelerator pedal to the car's computer, which then sends feedback to the throttle motor to drive the throttle plate. The opening size of the throttle plate determines the tachometer reading—the larger the throttle opening angle, the greater the air intake and the higher the engine speed. Other reasons for no response when stepping on the accelerator: Transmission failure: This is relatively easy to diagnose. If there is an issue with the transmission, the accelerator pedal may not depress, and the engine speed may suddenly increase from 2000 RPM to 4000 RPM. This happens because the power is cut off, causing the engine to suddenly have no load, leading to speed fluctuations. Common engine issues include problems with the transmission control system. In such cases, the engine warning light will illuminate, indicating stored faults. These faults can be read using a diagnostic tool.
