Why does the Honda CR-V engine shake when warm?

[Albert]

Honda CR-V engine shaking when warm is caused by ignition system issues and unstable oil pressure. Below are the reasons and solutions for Honda CR-V engine shaking. Severe engine carbon buildup: The most common cause of car shaking is a dirty throttle body or excessive carbon deposits on the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. In this situation, the engine will only start easily once the carbon deposits have absorbed enough gasoline to become saturated. After starting, the gasoline adsorbed on the carbon deposits is then drawn into the combustion chamber by the engine's vacuum suction, making the air-fuel mixture too rich. This fluctuation between lean and rich mixtures causes idle shaking after a cold start. Aging engine components: Car shaking can also be related to worn engine mounts. Engine mounts act as the engine's shock absorption system, responsible for absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations will transfer to the steering wheel and the cabin, causing shaking at idle.
