2. Visually inspect the engine mounts for cracks, separation, or excessive wear.
3. If damaged, remove the bolts securing the engine mount to the subframe and engine.
4. Replace with new engine mounts and torque to manufacturer specifications (usually around 40-50 ft-lbs).

3. Replace Spark Plugs and Ignition Coils

Tools Required: Spark plug socket, ratchet, torque wrench
Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the ignition coils and remove them using the socket.
3. Remove old spark plugs with a spark plug socket.
4. Install new spark plugs, torquing to the manufacturer's specification (typically around 13-15 ft-lbs).
5. Reinstall the ignition coils, ensuring they are seated properly.

4. Clean or Replace Fuel Injectors

Tools Required: Fuel injector cleaner kit or replacement injectors, socket set
Sub-steps:
1. If cleaning, disconnect the fuel rail and injectors.
