1. Locate the engine mounts (typically near the front and rear of the engine).
2. Use a socket set to remove the bolts securing the mounts to the engine and frame.
3. Replace any worn or damaged mounts with new ones.
4. Torque the bolts to the manufacturer's specifications (consult service manual for specific torque values).

3. Address Vacuum Leaks

Sub-steps:
1. Visually inspect all vacuum hoses and connections for cracks or disconnections.
2. Use a smoke machine or carburetor cleaner to check for leaks while the engine is running.
3. Replace any damaged hoses and ensure all connections are secure.

4. Inspect and Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the ignition coils using a socket set.
2. Check the spark plugs for wear; replace if they are excessively worn or fouled.
3. Install new spark plugs with the correct gap settings (consult specifications).
4. Reinstall the ignition coils and ensure they are securely fastened.

5. Clean or Replace Fuel Injectors

Sub-steps:
1. Remove the fuel injectors carefully from the intake manifold.
