Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical systems.

2. Inspect and Clean Air Intake

Remove the air filter housing and inspect the air filter; replace if dirty.
Clean the throttle body using throttle body cleaner and a soft cloth.
Reassemble the air intake system ensuring all connections are tight.

3. Check and Replace Fuel Filter

Locate the fuel filter (if applicable) and relieve fuel system pressure.
Disconnect the fuel lines from the filter using the appropriate tool.
Replace the old fuel filter with a new one, ensuring correct orientation.
Reconnect the fuel lines securely.

4. Inspect and Replace Spark Plugs

Remove the ignition coil cover or spark plug wires as needed.
Use a socket set to remove the old spark plugs.
Inspect the spark plugs for wear and replace them with the correct type and gap as specified by the manufacturer.
Reinstall the ignition coils or wires.

5. Test and Replace Ignition Coils (if necessary)

Use a multimeter to test the resistance of each ignition coil.
Replace any faulty coils with new ones, ensuring proper torque specifications during installation.
