my Skoda Octavia NFL (2020-Present) has poor acceleration, what could be causing this?

Solution

1. Preparation

• Gather all tools and parts needed for the repair.
• Disconnect the battery to ensure safety while working on electrical components.

2. Clean or Replace Air Filter

• Locate the air filter housing.
• Remove the air filter and inspect for dirt and debris.
• If dirty, either clean or replace with a new OEM air filter.
• Reinstall the air filter and secure the housing.

3. Fuel System Inspection

• Attach the fuel pressure gauge to the fuel rail.
• Start the engine and monitor the fuel pressure; it should be within specifications (consult manual for values).
• If pressure is low, check the fuel pump and fuel filter for issues.
• Replace the fuel filter if clogged.

4. Throttle Body Cleaning

• Remove the throttle body from the intake manifold (ensure all electrical connectors and hoses are detached).
• Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
• Reinstall the throttle body and reconnect all wires and hoses.

5. Inspect Ignition Components

• Remove spark plugs and inspect for wear or carbon deposits.
• Replace spark plugs if they are worn or fouled.
• Check ignition coils for proper function; replace any faulty coils.

6. Exhaust System Check

• Inspect the exhaust for any visible damage or restrictions.
• If the catalytic converter is suspected to be clogged, it may require replacement or cleaning.
