Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery to prevent electrical shorts during inspection.

2. Inspect and Replace Engine Mounts

Remove the Engine Cover (if applicable):
- Use a socket set to remove any screws or bolts securing the engine cover.
Lift the Vehicle:
- Use a jack to raise the front of the vehicle and secure it with jack stands.
Locate Engine Mounts:
- Identify the engine mounts; typically, there are two or three mounts securing the engine to the chassis.
Inspect Mounts:
- Check for cracks, tears, or excessive movement. If damaged, note which mounts need replacement.
Replace Damaged Mounts:
- Remove any bolts securing the damaged mount using a socket set.
- Replace with a new mount and torque the bolts to the manufacturer’s specifications (usually found in the service manual).

3. Clean and Replace Spark Plugs

Remove Ignition Coil:
- Disconnect the electrical connector and remove the mounting bolts using a socket set.
Remove Spark Plug:
- Use a spark plug socket and ratchet to carefully remove the spark plugs.
Inspect Spark Plugs:
- Look for wear or fouling on the electrodes. Replace if necessary.
Install New Spark Plugs:
- Gap the new spark plugs according to specifications and install them. Torque to manufacturer recommendations.

4. Check for Vacuum Leaks

Inspect Hoses:
- Visually inspect all vacuum hoses for cracks or disconnections.
Test with Smoke Machine:
- If available, use a smoke machine to introduce smoke into the intake and observe for any leaks.
Seal Leaks:
- Replace any damaged hoses and ensure all connections are secure.
