my Skoda Octavia NFL (2020-Present) doesn’t accelerate properly, what should I check?

Solution

1. Preparation

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

2. Clean or Replace Air Filter

• Remove the air filter housing cover using a socket set.
• Inspect the air filter; if dirty, replace it with a new one.
• Reinstall the housing cover securely.

3. Throttle Body Cleaning

• Locate the throttle body and remove the intake duct by loosening the clamps.
• Spray throttle body cleaner on a clean cloth and wipe the throttle plate and surrounding areas.
• Reassemble the intake duct and secure it with clamps.

4. Fuel Pressure Check

• Attach the fuel pressure gauge to the fuel rail's Schrader valve.
• Turn the ignition to the "ON" position without starting the engine to check the pressure reading.
• If the pressure is below specifications, consider replacing the fuel pump or fuel filter.

5. Inspect Ignition System

• Remove the spark plugs using a spark plug socket.
• Check the condition of the spark plugs; replace them if they show signs of wear.
• Test the ignition coils with a multimeter to ensure they are functioning correctly; replace any faulty coils.

6. Check for Vacuum Leaks

• Visually inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
• Use a smoke machine or carburetor cleaner to identify leaks while the engine is running.
• Replace any damaged hoses as necessary.
