Welcome! theres plenty to learn about your car here, I would start with reading some of the 2000+ section.

Welcome to the club!

Enjoy. Begin by changing plugs, wires and front O2 sensor. Change out all fluids.

After that, the fun begins.

Welcome from another 03 SSEi owner!! Got any pics?

Going off of what silverbullet said, start off by making sure all the items on this list are up to date, then we can go from there.
