Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Replace Spark Plugs

Sub-steps:
1. Disconnect the negative battery terminal to ensure safety.
2. Remove the ignition coil covers (if equipped).
3. Use a socket wrench to remove the spark plugs.
4. Inspect the old spark plugs for wear; replace if necessary.
5. Install new spark plugs, ensuring they are torqued to manufacturer's specifications (typically around 13-16 ft-lbs).
6. Reconnect the ignition coils and battery terminal.

3. Inspect and Replace Engine Mounts

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect engine mounts for cracks, tears, or excessive wear.
3. If damaged, remove the bolts securing the engine mount to the engine and subframe.
4. Install the new engine mounts and torque bolts to manufacturer's specifications.
5. Lower the vehicle back to the ground.

4. Clean or Replace Air Filter

Sub-steps:
1. Open the hood and locate the air filter housing.
2. Remove the air filter cover by unscrewing or unclipping it.
3. Inspect the air filter; if dirty, replace it with a new one or clean it if reusable.
4. Reattach the air filter housing cover securely.

5. Test and Repair Vacuum Leaks

Sub-steps:
1. Use a vacuum gauge to check for vacuum leaks at the intake manifold and associated hoses.
2. Inspect hoses for cracks and replace damaged hoses.
3. Use a carburetor cleaner spray to check for leaks: spray around the intake manifold while the engine is idling; if RPM changes, a leak is present.
