Beidou Star unstable idle speed troubleshooting methods generally include cleaning related components or repairing engine mechanical structures. The following is a related introduction about Beidou Star idle speed faults: 1. Causes: Mostly related to a dirty throttle. For cars with a throttle, if carbon deposits or other dirt accumulate in the throttle area, it will lead to reduced air intake. It could also be due to a damaged or stuck idle valve, a faulty computer board, or intake pipe leaks, resulting in unstable idle speed. 2. Precautions: Unstable car idle speed is mainly manifested by fluctuations in the tachometer needle at idle, pointing unstably, going up and down. Unstable idle speed is often accompanied by idle shaking. Normally, the engine idle speed can be determined, and the specific level depends on the tuning of the particular car model. Generally, if the idle speed is too high, fuel consumption will be relatively high, but if the idle speed is too low, the engine may shake or even stall.

Why Does the Car Jerk When Accelerating at Low Speeds?

The reasons why a car jerks when accelerating at low speeds are: 1. Excessive carbon deposits on the throttle, fuel injectors, or intake manifold. It is recommended to regularly clean carbon deposits; 2. Poor fuel quality leading to incomplete combustion; 3. Faulty spark plugs or ignition coils causing cylinder misfires, which require inspection and repair at a service center to avoid further safety hazards. For manual transmission models, jerking occurs when accelerating or decelerating while driving in a semi-clutch state. The deeper the throttle is pressed, the more pronounced the jerking sensation. For automatic transmission models, there is a slight jerking sensation when accelerating and upshifting, and the sensation is more noticeable when forcefully downshifting with a heavy throttle and then upshifting.
