How do I know if my Nissan Micra needs a tune-up?

I recently purchased a used Nissan Micra and I'm not sure if it's running efficiently. How can I tell if it needs a tune-up?

It's always a good idea to get a tune-up after purchasing a used car. You can check for warning signs like strange noises or a decrease in performance, but it's best to have a professional mechanic perform a diagnostic check to ensure everything is functioning properly.
