Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts during the repair.

2. Inspect and Repair Intake System

Tools Required: Socket set, torque wrench, vacuum gauge
Carefully remove the engine cover (if applicable) by unscrewing any fasteners.
Inspect the intake manifold and hoses for any cracks or disconnections.
If a vacuum leak is detected, replace the damaged hose or reconnect any loose components.

3. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth
Remove the air intake duct connected to the throttle body.
Spray throttle body cleaner onto a soft cloth and wipe the interior of the throttle body to remove carbon deposits.
Reattach the air intake duct securely.

4. Replace Air Filter (if necessary)

Tools Required: None (if using a hand-tightened air filter)
Locate the air filter housing and open it.
Remove the old air filter and replace it with a new one, ensuring it sits correctly in place.

5. Reassemble and Test

Reattach the engine cover and any components removed during the process.
Reconnect the negative battery terminal.
Start the engine and monitor for any sounds or warning lights before taking it for a test drive.
