Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Repair the Intake System

Tools Required: Socket set, screwdrivers, vacuum gauge, carburetor cleaner
Remove the air intake duct by loosening the clamps and disconnecting any electrical connectors.
Inspect the air filter; replace it if dirty or damaged.
Check the intake manifold and vacuum hoses for cracks or loose fittings. Tighten or replace as necessary.
If a vacuum leak is detected, replace the affected hose or seal.

3. Inspect and Repair the Exhaust System

Tools Required: Jack and jack stands, wrench set
Safely lift the vehicle and inspect the exhaust system from the manifold to the tailpipe.
Look for signs of rust, holes, or loose connections. Tighten or replace any loose clamps.
If a leak is found at the exhaust manifold, consider replacing the gaskets or the manifold itself.

4. Reassemble Components

Reattach the air intake duct and ensure all clamps and connectors are securely fastened.
Reconnect the battery.
