1. Motor mounts: Worn or broken motor mounts can cause the engine to vibrate excessively. Inspect the motor mounts for cracks or tears, and make sure they are securely attached to the engine and frame.
2. Transmission mount: A worn or broken transmission mount can also cause the engine to vibrate. Inspect the transmission mount for cracks or tears, and make sure it is securely attached to the transmission and frame.
3. Exhaust system: A loose or damaged exhaust system can cause rattling or buzzing noises. Inspect the exhaust system for any loose or damaged parts, and make sure that the exhaust hangers are securely attached.
4. Spark plugs: If the spark plugs are worn or damaged, they can cause the engine to run rough and vibrate. Inspect the spark plugs for wear or damage, and replace them if necessary.
5. Ignition coils: If the ignition coils are worn or damaged, they can cause the engine to run rough and vibrate. Inspect the ignition coils for cracks or damage, and replace them if necessary.
6. Throttle body: A dirty throttle body can cause the engine to run rough and vibrate. Clean the throttle body with a throttle body cleaner, and make sure that the throttle plate opens and closes smoothly.
If you are unable to find the cause of the noise and vibration, it is recommended to take your vehicle to a qualified mechanic for further diagnosis and repair.
