my Skoda Octavia NFL (2020-Present) loses power when accelerating, what could be wrong?

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the engine is off.
• Disconnect the battery for safety.

2. Address Fuel Delivery Issues

• Fuel Pressure Check:
  • Connect a fuel pressure gauge to the fuel rail.
  • Turn the ignition to the "ON" position without starting the engine and check the pressure.
  • If pressure is below specifications, inspect the fuel pump and filter for clogs or failure.
• Replace Fuel Filter (if necessary):
  • Locate the fuel filter, typically along the fuel line.
  • Depressurize the fuel system, then disconnect the filter.
  • Install the new filter, ensuring correct orientation and secure connections.

3. Clean or Replace Throttle Body

• Throttle Body Cleaning:
  • Remove the intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft brush to remove carbon deposits.
  • Reassemble the intake duct and ensure all connections are tight.
• Replacement (if cleaning is insufficient):
  • Disconnect the throttle body electrical connector.
  • Unbolt the throttle body from the intake manifold.
  • Install the new throttle body and reconnect the electrical connector.

4. Inspect and Replace Ignition Components

• Spark Plug Inspection:
  • Remove spark plug wires or coil packs.
  • Inspect spark plugs for wear or fouling; replace if necessary.
  • Reinstall spark plugs with a torque of 15-20 ft-lbs.
• Ignition Coil Testing:
  • Use a multimeter to test resistance in each ignition coil.
  • Replace any coil that does not meet specifications.

5. Check for Vacuum Leaks

• Inspect all vacuum hoses connected to the intake manifold.
• Replace any cracked or disconnected hoses and ensure all clamps are secure.
