What Causes Engine Shaking in Honda CRV?
2 Answers
Severe engine carbon deposits, ignition system issues, unstable oil pressure, aging engine components, etc. Severe engine carbon deposits: The most common cause of car shaking is a dirty throttle body or excessive carbon deposits in the fuel injectors. Ignition system issues: Check the working condition of spark plugs, high-voltage wires, and ignition coils. Poor ignition system performance or faulty spark plug firing can also lead to such symptoms. Unstable oil pressure: If you have already cleaned the engine carbon deposits, cleaned the throttle body, replaced the oil pads and spark plugs, but still notice body shaking at idle, it is recommended to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor for any abnormalities. Aging engine components: Car shaking can also be related to aging engine mounts.
I've handled quite a few Honda CR-V cases where engine shaking is indeed quite common. The main causes are ignition system issues, such as aged or eroded spark plugs, which lead to uneven cylinder ignition and noticeable shaking when driving. Next is the fuel system; clogged fuel injectors disrupt smooth fuel spraying, and excessive carbon buildup can also increase engine vibration. Then there's engine mount damage—when mounts age, their damping effect is lost, making even small bumps cause shaking. Poor fuel quality can also be problematic, like using low-grade fuel with impurities that cause unstable combustion. Neglecting regular maintenance often leads to these issues. I recommend first checking the spark plugs and air filter yourself—simply replacing them with new parts can improve the situation. If the shaking is frequent, it's best to visit a dealership for a comprehensive diagnosis to prevent minor issues from turning into major faults that could affect driving safety.
