Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Locate the engine and transmission mounts.
3. Visually inspect the mounts for cracks, tears, or excessive wear.
4. If damaged, remove the bolts securing the mounts using a socket set.
5. Replace with new mounts, ensuring proper alignment.
6. Tighten bolts to manufacturer specifications (refer to service manual for torque values).

3. Check and Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover (if applicable) to access the ignition components.
2. Disconnect the electrical connectors from the ignition coils.
3. Remove the bolts securing the coils and pull them out.
