Baojun 630, 15 months old, cleaned the accelerator twice and brushed the motherboard twice. What's the curve? . . The throttle assembly was also replaced once. .

Hello! Baojun 630 clutch pedal has a position sensor. If you don't meet the correct logical driving requirements for a long time, the pedal sensor will form a wrong driving habit memory, resulting in unstable engine idle speed. In addition, it may be the influence of the driving environment, and the intake dust is large, which leads to the throttle sticking and the engine idling instability.
