Solution

1. Preparation

Gather necessary tools and parts for repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Engine Mounts (if needed)

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Visually inspect engine mounts for cracks or separation.
3. To replace, remove the bolts securing the old mount to the engine and the chassis using a socket set.
4. Install the new engine mount and torque the bolts to manufacturer specifications (consult service manual for specific torque values).

3. Inspect and Replace Spark Plugs and Ignition Coils (if needed)

Sub-steps:
1. Remove the ignition coil cover (if applicable) to access the spark plugs.
2. Disconnect the ignition coils and carefully remove them.
3. Remove the spark plugs using a spark plug socket and inspect them for wear or fouling.
4. Install new spark plugs (gapped to specifications) and reattach the ignition coils.

4. Clean Throttle Body

Sub-steps:
1. Remove the air intake duct connected to the throttle body.
2. Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
3. Reattach the air intake duct and ensure all connections are secure.

5. Check for Vacuum Leaks

Sub-steps:
1. Inspect all vacuum hoses for cracks or disconnections.
2. Use a smoke machine or propane torch to detect leaks around the intake manifold and hoses.
3. Replace any damaged hoses or gaskets.
