What Causes Severe Vibration During Magotan Startup?

[HavenFitz]

Magotan car experiences severe vibration during startup due to the following specific reasons: 1. Excessive carbon buildup in the throttle body, fuel injectors, and intake manifold may cause severe startup vibration. 2. Heavy carbon deposits inside the engine can absorb a large amount of gasoline sprayed by the fuel injectors during startup, resulting in an overly lean air-fuel mixture and causing severe startup vibration. 3. Mechanical failures in components such as ignition coils, spark plugs, or fuel injectors leading to cylinder misfires; insufficient oil pressure or cylinder compression causing power loss can result in severe vibration during startup. 4. Oxidized or low-grade engine oil, primarily with poor low-temperature fluidity, fails to provide adequate cold-start protection for the engine, leading to severe vibration during startup.
