What Causes Body Shaking When the Odyssey Accelerates Rapidly to 40 km/h?

[LeKyle]

Body shaking when the Odyssey accelerates rapidly to 40 km/h may be caused by carbon buildup in the intake system, which means there is a large amount of carbon deposits near the valve seat and idle motor, leading to an overly rich or lean air-fuel mixture, or a dirty throttle body. Below are the specific reasons: Carbon buildup in the intake system: This refers to a large amount of carbon deposits near the valve seat and idle motor, causing the air-fuel mixture to become too rich or too lean. This will result in idle shaking, which is more noticeable during cold starts. Dirty throttle body: If there is excessive carbon buildup or dirt around the throttle valve, the cross-sectional area of the air passage will change, preventing the control unit from accurately regulating the idle air intake and causing the air-fuel mixture to become too rich or too lean. Other reasons: If you notice slight body shaking or deviation while driving, the first thing to consider is tire-related factors. It could be due to poor tire balance, and the owner should promptly perform a four-wheel alignment and dynamic balancing.
