Why does my Vauxhall Mokka's engine shake when idling?

I've noticed that whenever my car is stopped and the engine is running, it starts to shake. This hasn't happened before, and I'm worried there might be a bigger issue. What could be causing this and should I take it to a mechanic?

It's most likely due to a dirty or clogged air filter. This can cause imbalances in the air-fuel mixture, resulting in engine shaking. You should take it to a mechanic to have the air filter replaced and save you from any potential engine damage.

Another reason could be a faulty spark plug. Over time, spark plugs can wear out and cause the engine to shake. It's best to have them inspected and replaced if necessary. A mechanic can diagnose and solve this issue for you.

If your Mokka has a manual transmission, the shaking could be caused by a worn out clutch. A mechanic can check the clutch and replace it if needed.

It's also possible that the shaking is due to low engine oil levels. Check the oil level and top it off if needed. If the issue persists, it's best to have a mechanic inspect for any leaks or other engine issues.
