how to fix P0301 misfire code on Skoda Octavia NFL (2020-Present)

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the battery to prevent any electrical issues.
• Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Replace Spark Plug

• Tools Required: Socket set, spark plug socket, torque wrench
• Remove the ignition coil cover if applicable.
• Unscrew and remove the spark plug from cylinder 1.
• Inspect the spark plug for wear or damage; replace if necessary.
• Install the new spark plug and tighten to the manufacturer’s torque specification (typically around 20 Nm).
• Reattach the ignition coil.

3. Replace Ignition Coil

• Tools Required: Socket set, ratchet
• Disconnect the electrical connector from the ignition coil.
• Remove the mounting bolts and pull the ignition coil from the spark plug.
• Install the new ignition coil and secure it with bolts.
• Reconnect the electrical connector.

4. Test Fuel Injector

• Tools Required: Noid light or stethoscope
• Disconnect the fuel injector connector.
• Connect a noid light to the injector connector to check for pulse.
• If no pulse is detected, replace the injector; if pulse is present, the injector may need cleaning.
• Reconnect the injector connector.

5. Compression Test

• Tools Required: Compression tester
• Remove the spark plug and connect the compression tester to the cylinder.
• Crank the engine several times until the gauge stabilizes.
• Record the compression reading; it should be within the manufacturer's specifications (typically 120-200 psi).
• If the compression is low, further diagnostics may be needed for internal engine issues.
