How do I keep my Nissan Juke's engine running smoothly?

I've noticed some rough idle and hesitation in my Nissan Juke's engine. What steps can I take to ensure it runs smoothly?

Regularly check and change your oil according to the manufacturer's recommendations. This will ensure that your engine stays properly lubricated and running smoothly.

Keep an eye on your spark plugs and replace them as needed. They are important for proper combustion and can affect the performance of your engine if they are worn or fouled.
