1. Jack up the vehicle and secure it with jack stands.
2. Visually inspect the engine mounts for cracks or excessive wear.
3. Use a pry bar to check for movement in the mounts; replace if damaged.
Parts Required: New engine mounts (if damaged).

3. Check Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the ignition coil connectors and the bolts securing the coils.
2. Pull out the coils and inspect them for cracks or carbon tracking.
3. Remove the spark plugs and inspect for wear or fouling; replace if necessary.
4. Reinstall new or cleaned components.
Parts Required: New spark plugs and ignition coils (if needed).

4. Check Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
