Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, jack stands.
Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the engine mounts (typically found at the front and rear of the engine).
3. Visually inspect the mounts for cracks, tears, or excessive wear.
4. If damaged, use the socket set to remove the bolts securing the engine mounts.
5. Replace with new engine mounts and torque the bolts to the manufacturer's specifications (refer to repair manual for exact torque values).

3. Clean or Replace Spark Plugs

Tools Required: Spark plug socket, gap tool, torque wrench.
Sub-steps:
1. Remove the ignition coils by unscrewing the bolts and gently pulling them off the spark plugs.
2. Use the spark plug socket to remove the spark plugs.
3. Inspect the spark plugs for wear or carbon buildup; replace if necessary.
4. Check the gap on the new or cleaned plugs and adjust to manufacturer's specification.
5. Reinstall the spark plugs and ignition coils, torquing them to the specified values.

4. Check and Repair Vacuum Leaks

Tools Required: Vacuum gauge, basic hand tools.
Sub-steps:
1. Use a vacuum gauge to check for proper readings; abnormal readings indicate leaks.
2. Inspect all vacuum hoses for cracks or disconnections.
3. Replace any damaged hoses and ensure all connections are secure.
