why does my Skoda Octavia's engine shake when idling

Solution

1. Preparation

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

2. Inspect and Replace Spark Plugs

• Remove the ignition coils or spark plug wires.
• Use a spark plug socket to remove the spark plugs.
• Inspect the spark plugs for signs of wear or damage, and replace them with new ones if necessary.
• Ensure the new spark plugs are gapped correctly as per manufacturer specifications.
• Reinstall the spark plugs and reconnect the ignition coils or spark plug wires.

3. Check and Test Fuel Injectors

• Remove the fuel injector connectors.
• Use a multimeter to check the resistance of each injector; replace any that are outside specifications.
• Clean the injectors using an appropriate fuel injector cleaner or replace them if they are clogged or damaged.
• Reinstall the fuel injectors and reconnect the connectors.

4. Inspect Engine Mounts

• Visually inspect the engine mounts for cracks, tears, or separation.
• If damaged, remove the old engine mounts using a socket set.
• Install new engine mounts, ensuring they are tightened to the manufacturer's specified torque settings.

5. Test and Replace Ignition Coils

• Remove the ignition coils and inspect for cracks or carbon tracking.
• Test each coil's resistance using a multimeter; replace any that do not meet specifications.
• Reinstall the ignition coils, ensuring proper connections.
