Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool completely before starting work.

2. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to remove carbon deposits from the throttle body.
Reconnect the air intake duct securely.

3. Check and Replace Fuel Filter

Locate the fuel filter in the fuel line and relieve fuel system pressure.
Disconnect the fuel lines from the filter using a line removal tool.
Replace with a new fuel filter, ensuring proper orientation.
Reconnect the fuel lines and check for leaks.

4. Inspect and Replace Spark Plugs

Remove the ignition coils using a socket wrench.
Extract old spark plugs using a spark plug socket.
Inspect the old plugs for wear; replace with new spark plugs as needed.
Reinstall ignition coils and torque to manufacturer specifications.

5. Check for Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine or carburetor cleaner around hose connections while the engine runs to detect leaks.
Replace any damaged hoses.
