1. Engine mounts: The engine mounts are rubber isolators that help absorb vibration from the engine and prevent it from being transmitted to the rest of the vehicle. If the engine mounts are worn or damaged, they may not be able to do their job properly, resulting in vibration.
2. Spark plugs: Spark plugs that are worn or fouled can cause the engine to misfire, which can also lead to vibration.
3. Fuel injectors: Fuel injectors that are clogged or dirty can cause the engine to run lean or rich, which can also cause vibration.
4. Vacuum leaks: Vacuum leaks can cause the engine to run rough and vibrate.
5. Exhaust system: If the exhaust system is damaged or has a leak, it can cause the engine to resonate and vibrate.
I recommend taking your Honda to a qualified mechanic to have it diagnosed and repaired.
