Solution

1. Preparation

Gather tools and materials, including a smoke machine or propane torch, OBD-II scanner, and basic hand tools.
Ensure the engine is cool and disconnect the battery to prevent any electrical issues.

2. Inspect Vacuum Hoses

Use a flashlight to examine all vacuum hoses for cracks, wear, or loose connections.
Replace any damaged hoses with OEM or equivalent parts.
Reconnect any loose hoses securely.

3. Test with Smoke Machine

Connect the smoke machine to the intake manifold vacuum port.
Activate the machine and observe for smoke escaping from any connections or gaskets.
Identify any leaks and mark the areas for repair.

4. Repair Leaks

For hose leaks, cut the damaged section and replace it with a new hose of appropriate size.
If the intake manifold gasket shows signs of wear, remove the intake manifold to replace the gasket.
Clean any old gasket material from the mating surfaces before installing the new gasket.

5. Reassemble and Reconnect

Reinstall any components removed for access (e.g., intake manifold).
Reconnect all vacuum hoses securely.
Reconnect the battery and ensure everything is properly secured.
