Why is my Vauxhall Astra's engine shaking while idling?

I recently noticed that my Vauxhall Astra's engine is shaking quite noticeably while idling. What could be causing this issue and how can I fix it?

The shaking could be caused by a worn out spark plug or spark plug wires. You should get them checked and replaced if necessary.

Another possible cause could be a clogged air filter. Try replacing it and see if the engine performance improves.

It could also be an issue with the engine mounts. If they are worn out, they can cause the engine to shake. Get them inspected and replaced if necessary.
