my Skoda Octavia's engine stalls while driving, what should I do?

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Fuel Filter

• Locate the fuel filter in the fuel line.
• Use a socket set to disconnect fuel lines from the filter; be cautious of fuel spillage.
• Remove the old fuel filter and install the new one, ensuring the arrows on the filter indicate the correct flow direction.
• Reconnect the fuel lines securely.

3. Check and Replace Spark Plugs

• Remove the ignition coil cover if applicable.
• Use a spark plug socket to remove the spark plugs from the engine.
• Inspect the old spark plugs for wear and carbon buildup; replace them with new ones as necessary, torquing to the manufacturer's specifications (usually around 15-20 ft-lbs).
• Reinstall the ignition coil and cover.

4. Inspect Fuel Pump

• Check the fuel pump relay and fuse for any signs of damage.
• If necessary, access the fuel pump through the rear seat or trunk area, disconnect the electrical connector, and remove the pump unit.
• Test the fuel pump with a multimeter for continuity and replace if faulty.

5. Clean Air Intake System

• Remove the air intake duct and clean the throttle body using throttle body cleaner.
• Inspect the air filter; replace it if it is dirty or clogged.
