Solution

1. Preparation

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

2. Replace Worn Engine Mounts

Sub-step 1: Lift the vehicle using a jack and secure it with jack stands.
Sub-step 2: Use a socket set to remove the bolts securing the engine mounts to the engine and frame.
Sub-step 3: Replace the old mounts with new ones, ensuring they are aligned properly.
Sub-step 4: Torque the bolts to the manufacturer's specifications.

3. Replace Spark Plugs and Ignition Coils (if necessary)

Sub-step 1: Remove the engine cover (if applicable) using a socket set.
Sub-step 2: Disconnect the ignition coil connectors and remove the coils using a socket.
Sub-step 3: Remove the spark plugs using a spark plug socket and inspect them for wear.
Sub-step 4: Install new spark plugs (set gap as per manufacturer specifications) and reinstall ignition coils.

4. Clean Throttle Body

Sub-step 1: Remove the air intake duct to access the throttle body.
Sub-step 2: Spray throttle body cleaner onto a clean cloth and wipe the throttle body interior.
Sub-step 3: Reinstall the air intake duct and ensure all connections are secure.

5. Check and Repair Vacuum Leaks

Sub-step 1: Use a vacuum gauge to check the engine's vacuum levels; normal levels should be steady.
Sub-step 2: Inspect and replace any cracked or disconnected vacuum hoses.
