my Skoda Octavia NFL (2020-Present) stalls while driving what should I do

Solution

1. Preparation

• Gather the necessary tools and parts.
• Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Address Fuel System Issues

• Fuel Pump Inspection:
  • Locate the fuel pump (usually in the fuel tank).
  • Disconnect the electrical connector and inspect for corrosion.
  • Use a fuel pressure gauge to check fuel pressure; compare readings to manufacturer specifications.
• Fuel Filter Replacement:
  • If the fuel filter is clogged, replace it by locating the filter and using a socket set to remove it.
  • Install a new filter, ensuring proper orientation, and reconnect fuel lines.

3. Inspect and Clean the Air Intake System

• Remove the air intake duct connected to the throttle body.
• Inspect the air filter; replace if dirty.
• Clean the throttle body using throttle body cleaner and a soft cloth, ensuring not to damage any sensors.

4. Check and Replace Ignition System Components

• Remove the ignition coil cover (if applicable) and inspect spark plugs for wear or carbon buildup.
• Replace faulty spark plugs with the correct specifications (refer to the vehicle manual for gap settings).
• Test ignition coils with a multimeter for proper resistance; replace any faulty coils.

5. Verify Electrical System

• Check battery voltage with a multimeter; it should be around 12.6 volts when fully charged.
• Inspect the alternator belt for wear and ensure proper tension.
• Replace the battery or alternator if they are not functioning within specifications.
