Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Engine Mounts

Sub-steps:
1. Raise the vehicle safely using jack stands.
2. Locate the engine mounts; typically found at the front and rear of the engine.
3. Visually inspect the mounts for cracks, tears, or any signs of fluid leaks.
4. If damaged, remove the bolts securing the mounts using a socket set.
5. Replace with new engine mounts, ensuring proper alignment.
6. Torque the bolts to the manufacturer’s specifications (usually around 30-50 Nm).

3. Address Vacuum Leaks

Sub-steps:
1. Inspect all vacuum hoses connected to the intake manifold.
2. Replace any cracked or damaged hoses with new ones.
3. Use a smoke machine to detect any hidden leaks in the intake system.
4. Ensure all connections are tight and free of debris.

4. Replace Ignition Components

Sub-steps:
1. Remove the engine cover to access the ignition coils and spark plugs.
2. Disconnect the ignition coil connectors and remove the coils.
3. Replace old spark plugs with new ones, ensuring proper gap specification (usually around 0.7-0.8 mm).
4. Reinstall the ignition coils, securing them in place.

5. Check and Clean the Throttle Body

Sub-steps:
1. Remove the air intake duct to access the throttle body.
2. Inspect for carbon buildup; if present, clean with throttle body cleaner and a soft cloth.
3. Reinstall the duct and ensure all clamps are secured.
