Solution

1. Preparation

Gather necessary tools and parts.
Allow the engine to cool before starting repairs.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, floor jack, jack stands.
Steps:
1. Raise the vehicle using a floor jack and secure it with jack stands.
2. Locate the engine mounts (typically found on both sides of the engine and under the transmission).
3. Inspect the mounts for cracks or signs of fluid leakage. If damaged, proceed to replace them.
4. Remove the bolts securing the damaged mounts using a socket wrench.
5. Carefully lift the engine slightly using the floor jack to relieve pressure on the mounts.
6. Install the new engine mounts, aligning them correctly, and torque the bolts to manufacturer's specifications (usually around 40-60 ft-lbs).

3. Clean or Replace Spark Plugs

Tools Required: Spark plug socket, torque wrench, gap gauge.
Steps:
1. Remove the engine cover if applicable.
2. Disconnect the ignition coils from the spark plugs.
3. Use the spark plug socket to remove the spark plugs.
4. Inspect the plugs for wear; replace if worn or fouled.
5. Ensure the new plugs are gapped correctly and install them, torquing to manufacturer specifications (typically around 13-16 ft-lbs).

4. Check and Repair Vacuum Leaks

Tools Required: Vacuum gauge, hose clamp pliers.
Steps:
1. Inspect all vacuum hoses for cracks or disconnections.
2. Use a vacuum gauge to test the intake manifold for leaks.
3. Replace any damaged hoses and ensure all connections are secure.
