Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (negative terminal) for safety.

2. Inspect and Repair the Air Intake System

Tools Required: Socket set, pliers, screwdrivers
Remove the air intake duct by loosening the clamps and disconnecting it from the throttle body.
Check for cracks or holes in the duct and replace if necessary.
Inspect the air filter and clean or replace it if dirty.

3. Check and Replace Vacuum Lines

Locate vacuum lines connected to the intake manifold.
Tools Required: Pliers, vacuum tester
Inspect each line for signs of wear or cracking; replace any damaged lines.
If no visible damage is found, use a vacuum tester to ensure that there are no leaks.

4. Inspect the Exhaust System

Tools Required: Jack and jack stands, socket set
Safely lift the vehicle and inspect the exhaust system from the manifold to the tailpipe.
Look for any holes, rust, or loose connections that could cause a whooshing sound.
Tighten any loose bolts or replace damaged sections of the exhaust.

5. Reassemble and Test

Reattach the air intake duct securely.
Reconnect the battery.
Start the engine and take the vehicle for a test drive to confirm that the whooshing sound has been resolved.
