Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Replace Engine Mounts (if necessary)

Tools Required: Socket set, torque wrench, jack and jack stands.
Locate the engine mounts; they are typically positioned between the engine and the frame.
Use the jack to support the engine gently.
Remove the bolts securing the engine mount to the engine and frame using the socket set.
Inspect the mounts for cracks or excessive wear. Replace if damaged.
Install new mounts and torque the bolts to the manufacturer's specifications.

3. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth, and a screwdriver.
Remove the air intake duct connected to the throttle body.
Use the throttle body cleaner to spray the inside of the throttle body while opening the throttle plate manually.
Wipe down all surfaces with a soft cloth to remove carbon buildup.
Reassemble the intake duct.

4. Inspect and Replace Spark Plugs/Ignition Coils (if necessary)

Tools Required: Socket set, torque wrench, dielectric grease.
Remove the engine cover if applicable.
Disconnect the ignition coils and remove them using the socket set.
Remove the spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace if necessary.
Apply dielectric grease to the ignition coil boots and reinstall both the coils and plugs, torquing to the manufacturer's specifications.

5. Check and Repair Vacuum Leaks

Tools Required: Vacuum gauge or smoke machine (optional).
Inspect all vacuum hoses for cracks or disconnections.
Replace any damaged hoses.
If using a smoke machine, introduce smoke into the intake to identify leaks visually.
