First of all....don't just go replacing parts because the idiot at the local parts palace tells you too. If it was your gas cap (which didn't need replacing) it would have gone off after a couple of days. Secondly, NOW it may just be a leaky vacume hose. My '00 had one right up front. I put some electrical tape on it and light went off. Just because codes are showing up doesn't mean you need to replace parts. You will go broke buying parts you don't need. If your altenator is starting to go (which is common) you will start getting a bunch of different codes. If you changed battery without altenator, problems such as this are common. Altenators are not cheap. ($225) Find a reliable shop and stick with them. Also this site helps tremendously.
