my Skoda Octavia loses power on the highway what could be wrong

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery to ensure safety while working on electrical components.

2. Address Fuel System Issues

• Fuel Pressure Check
  • Connect a fuel pressure gauge to the fuel rail.
  • Turn the ignition to the "ON" position (do not start the engine) and record the pressure reading.
  • If pressure is below specifications, inspect the fuel pump and fuel filter for clogs or failures.
• Fuel Pump Replacement (if necessary)
  • Relieve fuel system pressure by removing the fuel pump relay.
  • Disconnect the battery again.
  • Remove the fuel tank to access the fuel pump.
  • Replace the fuel pump and reassemble the tank.

3. Clean or Replace Air Filter

• Locate the air filter housing and remove it.
• Inspect the air filter; if dirty or clogged, replace with a new one.
• Reassemble the air filter housing securely.

4. Inspect and Replace Ignition Components

• Remove the ignition coils and inspect for damage or wear.
• Replace any faulty ignition coils and spark plugs as necessary.
• Reinstall all components securely.

5. Examine and Clean Throttle Body

• Remove the air intake duct to access the throttle body.
• Clean the throttle body with throttle body cleaner and a soft cloth to remove carbon buildup.
• Reattach the air intake duct and ensure all connections are secure.

6. Check Exhaust System

• Inspect the exhaust system visually for any signs of damage or obstruction.
• If a clogged catalytic converter is suspected, perform a backpressure test.
• Replace the catalytic converter if it is found to be blocked.
