What causes the engine to idle roughly in a Kia Picanto?

I have a Kia Picanto and I've noticed that it has been idling roughly lately. It's been running a bit shaky and it seems like it struggles to maintain a consistent idle speed. What could be causing this issue? Is it normal or should I get it checked out?

It's not normal for a car to idle roughly. You should definitely get it checked out by a mechanic. It could be a sign of an underlying issue.

There are a few potential causes for rough idle in a Kia Picanto. It could be due to a vacuum leak, dirty fuel injectors, a faulty sensor, or a problem with the ignition system. It's best to get it diagnosed and fixed as soon as possible to prevent any further damage to your car.

I had the same issue with my Kia Picanto before. The rough idle was caused by a clogged air filter. After getting it replaced, the idle went back to normal. So you might want to check your air filter as well.
