What is the most common cause of engine misfire in a Kia Picanto?

I've noticed my car is having some trouble starting and seems to be running rough. I'm concerned it might be a serious problem. Can you give me some advice on what might be causing this issue?

The most common cause of engine misfire in a Kia Picanto is a faulty spark plug or ignition coil. These should be checked and replaced if necessary as part of regular maintenance.

Another common cause of engine misfire is a dirty or clogged fuel injector. Keeping up with regular fuel injector cleaning can help prevent this issue.

Low fuel pressure or a lack of proper air intake can also cause engine misfire. Make sure to follow the recommended fuel and air filter replacement schedule to prevent these issues.

If none of these solutions seem to fix the problem, it may be a more serious issue with the engine itself. It's best to have a professional mechanic diagnose and address any potential engine issues.
