What are the reasons for the car accelerating without pressing the gas pedal?

[StIsla]

The reasons for the car accelerating without pressing the gas pedal are: 1. The throttle cable has not returned to its original position. You can remove the cable and pour lubricating oil from the upper end of the cable to allow the oil to slowly penetrate into the cable tube; 2. The idle motor is stuck or has lost memory. It needs to be cleaned or replaced and then re-learned, which requires the use of a diagnostic computer for initialization settings; 3. Excessive carbon buildup in the throttle body, which requires cleaning. Precautions for pressing the gas pedal include: 1. Press and release the gas pedal gently and slowly; 2. The release of the clutch should be closely coordinated with pressing the gas pedal for agile movement; 3. Choose the appropriate gear to ensure the engine runs most of the time at medium speed and larger throttle opening to save fuel; 4. Before the car stops or shuts down, the gas pedal should be released first, and avoid suddenly revving the engine without load.
