What Causes Engine Vibration in Nissan Teana?

[LeJulianna]

Reasons for engine vibration in Nissan Teana: 1. Severe engine carbon deposits, dirty throttle body, or excessive carbon buildup in fuel injectors. When there is too much carbon deposit inside the engine, the gasoline sprayed by the cold-start injector will be largely absorbed by the carbon deposits; 2. Engine misfire: This mainly refers to one or more cylinders in the engine not functioning properly; 3. The combustible mixture in the engine fluctuates between lean and rich, causing idle vibration after cold starts. The lower the temperature, the more fuel is required for a cold start, and the presence of carbon deposits will significantly affect the smoothness of the cold start. The Teana is a flagship mid-to-high-end luxury sedan under NISSAN. In terms of body dimensions, its length, width, and height are 4.868 meters, 1.830 meters, and 1.490 meters respectively.
