2. Visually inspect engine and transmission mounts for cracks or excessive wear.
3. If found faulty, remove the bolts securing the mounts using a socket set.
4. Replace with OEM or high-quality aftermarket mounts.
5. Torque the new mounts to the specified values in the service manual.

4. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if necessary.
2. Disconnect the ignition coils from the spark plugs.
3. Use a spark plug socket to remove the old spark plugs.
4. Inspect the plugs for wear or carbon buildup.
5. Install new spark plugs, ensuring the gap is set to manufacturer specifications.
