Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent any electrical shorts.
Ensure the vehicle is parked on a level surface and securely supported.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Locate the engine mounts (typically found on the front, rear, and sides of the engine).
2. Using a socket set, remove the bolts securing the engine mounts to the engine and chassis.
3. Carefully lift the engine slightly with a jack to relieve pressure on the mounts.
4. Remove the old mounts and install new ones.
5. Torque the bolts to the manufacturer's specifications (typically around 50-60 ft-lbs).

3. Address Vacuum Leaks

Sub-steps:
1. Inspect hoses and connections in the intake system for cracks or disconnections.
2. Use carburetor cleaner to spray suspected areas while the engine is running; a change in RPM indicates a leak.
3. Replace damaged hoses or secure loose connections as necessary.

4. Replace Spark Plugs and Ignition Coils

Sub-steps:
1. Remove the engine cover (if applicable) using a socket set.
2. Disconnect the ignition coils by removing the electrical connectors.
3. Unscrew the ignition coils and remove them.
4. Remove the old spark plugs using a spark plug socket.
5. Install new spark plugs, ensuring they are properly gapped according to specifications.
6. Reinstall the ignition coils and reconnect the electrical connectors.

5. Clean Throttle Body

Sub-steps:
1. Locate the throttle body and disconnect the air intake hose (use a screwdriver if necessary).
2. Use throttle body cleaner and a clean rag to remove carbon buildup inside the throttle body.
3. Reattach the air intake hose and ensure all connections are secure.
