my Skoda Octavia NFL (2020-Present) feels like it's losing power on the highway

Solution

1. Preparation

• Gather necessary tools and park the vehicle on a flat surface.
• Disconnect the battery to ensure safety during repair.
• Tools Required: OBD-II scanner, socket set, fuel pressure gauge, multimeter, cleaning supplies.

2. Clean/Replace Air Filter

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

3. Test and Replace Fuel Pump (if needed)

• Connect the fuel pressure gauge to the fuel rail.
• Turn the ignition on (without starting the engine) and check the pressure reading.
• If the pressure is below specifications, replace the fuel pump.
  • Drain fuel from the tank, disconnect the battery, and remove the fuel lines and pump assembly.
  • Install the new fuel pump, reconnect the lines, and refill the tank.

4. Inspect and Replace Spark Plugs

• Remove the ignition coil packs using the socket set.
• Extract the spark plugs using a spark plug socket.
• Inspect the spark plugs for wear or fouling; replace them if necessary.
• Ensure proper gap settings as per manufacturer specifications before reinstallation.

5. Clean or Replace Mass Airflow Sensor

• Disconnect the electrical connector from the MAF sensor.
• Remove the sensor from the intake duct.
• Clean the sensor with MAF cleaner or replace it if damaged.
• Reinstall the sensor and reconnect the electrical connector.
