4. Replace any damaged components such as the air filter or intake duct.

3. Address Vacuum Leaks

Tools Required: Vacuum gauge, hose clamps, replacement hoses.
Steps:
1. Connect the vacuum gauge to a vacuum port on the intake manifold.
2. Start the engine and observe the gauge for fluctuations indicating a leak.
3. If a leak is detected, visually inspect the vacuum hoses for cracks or disconnections and replace as necessary.

4. Clean Throttle Body

Tools Required: Throttle body cleaner, soft cloth, socket set.
Steps:
1. Remove the throttle body from the intake manifold by unscrewing the mounting bolts.
2. Clean the throttle plate and bore using throttle body cleaner and a soft cloth.
