What Causes Idle Shaking?

Causes of idle shaking include severe engine carbon buildup, ignition system issues, unstable oil pressure, and aging engine components. The details are as follows: 1. Severe engine carbon buildup: Excessive carbon deposits in the engine can lead to poor engine performance, increased fuel consumption, and even difficulty starting. Over time, this can cause significant damage to the vehicle. Engine carbon buildup is primarily caused by poor driving habits, such as prolonged idling, aggressive acceleration and braking, low-quality fuel, driving at high gears with low speeds, and lack of regular maintenance. 2. Ignition system problems: When certain components or wiring in the car's ignition system experience open circuits, short circuits, insufficient primary current, low secondary voltage, or failed ignition timing adjustments, the engine's operation becomes unstable. This results in poor acceleration performance, reduced power and fuel efficiency, and can also cause idle shaking. 3. Unstable oil pressure: Many factors can lead to unstable engine oil pressure, such as insufficient oil, dirty oil, thinning oil, oil pipe leaks, damaged oil pumps, or excessive wear of oil pump components. If the engine continues to operate under low oil pressure, severe cases may cause the engine to "burn out the bearings," rendering the engine unable to start and requiring bearing scraping or replacement.
