Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the engine cover if applicable.
2. Disconnect the ignition coils by unclipping the electrical connectors.
3. Remove the bolts securing the ignition coils and take them out.
4. Use a spark plug socket to remove the old spark plugs.
5. Inspect the spark plugs for wear; replace with OEM or equivalent spark plugs if necessary.
6. Install new spark plugs to the specified torque (typically 13-15 lb-ft).
7. Reinstall the ignition coils and reconnect electrical connectors.

3. Inspect Engine Mounts

Sub-steps:
1. Visually inspect engine mounts for cracks, breaks, or excessive wear.
2. Use a pry bar to check for movement in the mounts; they should not allow excessive engine movement.
3. If damaged, remove the fasteners securing the engine mount to the frame and engine.
4. Replace with new mounts and tighten fasteners to the manufacturer's specifications.

4. Check and Repair Vacuum Leaks

Sub-steps:
1. Inspect all vacuum hoses for cracks or disconnections.
2. If leaks are found, replace the damaged hoses with new ones.
3. Use a smoke machine or propane torch (without igniting) to detect leaks in hard-to-reach areas.
4. Reseal or replace components as necessary.
