Solution

1. Preparation

Tools Required: OBD-II scanner, vacuum gauge, smoke machine, socket set, screwdrivers.
Disconnect the negative battery terminal to ensure safety before starting any work.

2. Inspect and Repair Intake Components

Step 1: Remove the air intake duct.
- Loosen the clamps with a screwdriver and detach the duct from the throttle body and air filter box.
Step 2: Inspect the intake hoses for cracks or loose connections.
- Replace any damaged hoses with OEM parts ensuring a proper fit.
Step 3: Clean or replace the air filter.
- If the filter is dirty, replace it with a new one to improve airflow.

3. Test for Vacuum Leaks

Step 1: Use a smoke machine to introduce smoke into the intake system.
- Observe for smoke escaping from any cracks or loose connections, indicating a vacuum leak.
Step 2: If a leak is found, replace the affected components (hoses, gaskets, or seals).

4. Inspect Throttle Body and PCV System

Step 1: Remove the throttle body.
- Unbolt and disconnect any electrical connectors before carefully removing it from the intake manifold.
Step 2: Clean the throttle body using throttle body cleaner.
- Use a soft cloth to wipe away carbon deposits; ensure the throttle plate moves freely.
Step 3: Check the PCV valve operation.
- Remove the PCV valve, shake it, and listen for a rattle; replace if faulty.
