Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Visual Inspection

Use a flashlight to inspect all vacuum lines connected to the intake manifold, throttle body, and other components.
Replace any damaged or cracked hoses with new vacuum hose of the same diameter.

3. Smoke Test

Connect a smoke machine to the intake system.
Activate the smoke machine and observe for smoke escaping from any areas, which indicates a vacuum leak.
If leaks are found, mark the locations for repair.

4. Repair Areas of Leakage

For hose replacements, remove the affected hoses and install new ones, ensuring they are secured with hose clamps.
If the intake manifold gasket is leaking, remove the intake manifold by following the manufacturer's service manual for torque specifications and removal procedures.
Clean the mating surfaces and install a new gasket, ensuring proper alignment.

5. Reassembly

Reinstall the intake manifold and any other components removed during the process.
Reconnect all vacuum lines securely and double-check connections.
Reconnect the negative battery terminal.
