Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery to avoid any electrical shorts.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt and damage.
If dirty, clean it with compressed air or replace it with a new one.
Reassemble the air filter housing securely.

3. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter along the fuel line.
Use a wrench to disconnect the fuel lines carefully, allowing any residual fuel to drain.
Remove the old filter and install a new one, ensuring proper orientation.
Reconnect the fuel lines and check for leaks.

4. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Ensure the throttle plate moves freely without obstruction.
Reassemble the intake duct securely.

5. Inspect and Test Ignition Components

Remove the spark plugs using a socket set and inspect for wear or carbon buildup.
Replace worn or damaged spark plugs with OEM specifications.
Test ignition coils with a multimeter to ensure they are functioning correctly.
Reinstall the spark plugs and ignition components.
