my Skoda Octavia NFL (2020-Present) is losing power when accelerating, what's wrong?

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter.
• Ensure that the vehicle is parked on a flat surface and the engine is cool.
• Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Clean or Replace Air Filter

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

3. Fuel System Inspection

• Connect a fuel pressure gauge to the fuel rail.
• Start the engine and monitor the fuel pressure; it should match manufacturer specifications (refer to the vehicle manual).
• If pressure is low, check for fuel pump operation and replace the fuel filter if necessary.
• Replace the fuel pump if it is not functioning properly.

4. Clean MAF Sensor

• Locate the MAF sensor in the air intake system.
• Carefully remove the MAF sensor using the appropriate tools.
• Clean the sensor using a specialized MAF cleaner spray; do not touch the sensor element.
• Reinstall the MAF sensor securely.

5. Throttle Body Cleaning

• Remove the intake hose connected to the throttle body.
• Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
• Reconnect the intake hose and ensure all clamps are tightened properly.

6. Inspect and Replace Ignition Components

• Remove the ignition coils using a socket set.
• Inspect spark plugs for wear; replace them if necessary.
• Test ignition coils for resistance using a multimeter and replace any faulty coils.
