Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean or Replace the Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect it for dirt and damage.
Clean the air filter housing with a vacuum or damp cloth.
Replace the old filter with a new one if necessary.

3. Inspect and Clean the Throttle Body

Reconnect the battery terminal temporarily to test the throttle response.
Disconnect the throttle body connector and remove the throttle body using the socket set.
Clean the throttle body with throttle body cleaner and a soft brush.
Reinstall the throttle body and reconnect the electrical connector.

4. Test and Replace Ignition Components

Remove the spark plugs using a socket wrench and inspect for wear or fouling.
Replace any worn or damaged spark plugs with OEM specifications.
Test the ignition coils using a multimeter to check for proper resistance; replace if faulty.

5. Check and Repair Vacuum Leaks

Inspect all vacuum hoses visually and replace any that are cracked or damaged.
Use a smoke machine or carburetor cleaner around vacuum connections to check for leaks.
Seal any identified leaks with appropriate vacuum hose or sealant.
