Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Sub-steps:
1. Locate the engine mounts (typically found at the front, rear, and sides of the engine).
2. Use a socket set to remove the bolts securing the engine mounts to the engine and chassis.
3. Carefully lift the engine slightly using a jack or pry bar to relieve tension on the mounts.
4. Remove the old mounts and replace them with new ones.
5. Reinstall the bolts and torque them to the manufacturer’s specifications (typically around 40-50 ft-lbs, but check the service manual).

3. Inspect and Replace Spark Plugs

Tools Required: Socket set, spark plug socket, torque wrench
Sub-steps:
1. Remove the ignition coils by unscrewing the retaining bolts.
2. Gently pull out the coils and set them aside.
3. Use a spark plug socket to remove the spark plugs.
4. Inspect the old spark plugs for wear; replace with new plugs if necessary (typically use OEM specifications).
5. Install new spark plugs and torque them to 13-15 ft-lbs.
6. Reinstall the ignition coils, securing them with bolts.

4. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth, screwdriver
Sub-steps:
1. Locate the throttle body and remove the intake duct by loosening the clamps.
2. Spray throttle body cleaner onto a soft cloth and gently wipe the interior of the throttle body.
3. Ensure all carbon deposits are removed and the throttle plate can move freely.
4. Reattach the intake duct and secure it with clamps.
