What Causes Idle Shaking in the Mondeo?
1 Answers
Causes of idle shaking in the Mondeo 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. The root causes of engine carbon buildup are 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 issues: Problems in the car's ignition system, such as open or short circuits in certain components or wiring of the ignition coil, insufficient primary current, low secondary voltage, or failed ignition timing adjustment, can all result in unstable engine operation. This worsens acceleration performance, reduces power and fuel efficiency, and also leads to idle shaking. 3. Unstable oil pressure: Many factors can cause unstable engine oil pressure, such as insufficient oil, dirty oil, thinning oil, leaking oil pipes, damaged oil pumps, or excessive wear of their components. If the engine continues to operate under low oil pressure, severe cases may lead to "bearing seizure," rendering the engine unable to start and requiring bearing scraping or replacement.
