Why is my Kia Picanto's engine shaking while idle?

I've noticed that whenever I stop at a red light or stop sign, the engine on my Kia Picanto starts shaking and feels like it's going to stall. What could be causing this issue?

One possible cause could be a dirty or clogged fuel filter. I would recommend getting it checked and replaced if necessary.

Another possibility is a vacuum leak. Check all the hoses and connections in the engine bay for any cracks or leaks.

It could also be an issue with the spark plugs. Make sure they are clean and in good condition. If they are worn out, replace them.
