What Causes the Engine to Stall When Releasing the Accelerator?

[RebeccaLee]

The reason the engine stalls when releasing the accelerator is: excessive carbon buildup in the engine's throttle body, leading to poor fuel flow. Solution: 1. First, remove the vehicle's intake pipe; 2. After removing the intake pipe, you can see the throttle opening, which is now closed; 3. Use a wrench to open the throttle; 4. Spray cleaning agent into the throttle body; 5. Use a clean tissue to wipe the inside of the throttle body clean. Stalling when releasing the accelerator is essentially idle stalling. Idling is an operating condition of the engine, referring to the state when the engine runs without pressing the accelerator. During idle, the engine speed can vary, with lows around 600 RPM and highs reaching over 800 RPM, depending on the number of cylinders and the computer programming. If the speed is too low, the engine may shake or even stall.
