my Skoda Octavia NFL (2020-Present) has poor fuel economy, what could be wrong

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface.
• Disconnect the battery for safety.

2. Replace Air Filter

• Locate the air filter housing.
• Remove the housing cover by unscrewing or unclipping it.
• Take out the old air filter and inspect it for dirt and damage.
• Install the new air filter, ensuring it fits snugly in the housing.
• Reattach the housing cover securely.

3. Clean Throttle Body

• Remove the air intake duct connected to the throttle body.
• Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
• Ensure no debris falls into the intake manifold.
• Reattach the air intake duct and secure with clamps.

4. Replace Spark Plugs

• Locate the ignition coils by removing any necessary engine covers.
• Disconnect the electrical connectors from the ignition coils.
• Unbolt and remove the ignition coils.
• Use a spark plug socket to remove the old spark plugs.
• Install new spark plugs to the manufacturer’s torque specifications (typically around 15-20 lb-ft).
• Reinstall the ignition coils and reconnect the electrical connectors.

5. Check Tire Pressure

• Use a tire pressure gauge to check each tire.
• Inflate tires to the manufacturer’s recommended PSI, usually found on the driver’s door jamb.
• Inspect tires for uneven wear or damage that may require rotation or replacement.
