Why is my Kia ProCeed experiencing irregular engine idling?

I recently purchased a Kia ProCeed and have noticed that the engine often idles inconsistently, causing vibrations and a rough driving experience. What could be causing this and how can I fix it?

Irregular engine idling is a common issue with Kia ProCeed that is often caused by a faulty idle air control valve or a dirty throttle body. It is important to have a professional mechanic take a look at these components and clean or replace them if necessary.

Another possible cause of irregular engine idling in your Kia ProCeed could be a vacuum leak. This can be fixed by locating and repairing the leak, which can be a bit tricky. It's recommended to have a mechanic do this for you to ensure the leak is properly sealed.

In some cases, the issue may be with the fuel system such as a clogged fuel filter or a malfunctioning fuel pressure regulator. These components can also cause irregular engine idling and should be inspected and replaced if needed.
