Why is my Kia Picanto's engine making a strange noise while idling?

I noticed that my Kia Picanto's engine is making a strange noise while idling. It sounds like a rattling or knocking sound. What could be causing this and should I be worried?

It could be due to a loose belt or an issue with the timing chain. I suggest bringing your car to a mechanic for further inspection to avoid any potential damage to your engine.

I had a similar issue with my Kia Picanto and it turned out to be a problem with the spark plugs. I recommend checking the spark plugs and replacing them if necessary. This should resolve the strange noise.

It is always best to err on the side of caution when it comes to strange noises coming from your car's engine. I advise having a professional mechanic take a look at your Kia Picanto to diagnose and fix the issue.
