Remove the air intake duct and throttle body.
Use throttle body cleaner to remove carbon buildup from the throttle body.
Inspect the air filter and replace if dirty or clogged.

4. Check Ignition System

Remove spark plugs using a spark plug socket.
Inspect for wear or carbon buildup; replace if damaged.
Test ignition coils with a multimeter; replace if resistance is outside specifications.

5. Inspect Vacuum Lines

Visually inspect all vacuum lines for cracks, wear, or disconnections.
Replace any damaged vacuum lines to ensure proper engine function.
