First with the onboard lights for your CEL you can replace that easy, someone has writen a fix for this I used and alo did a write up. Look for it ots out there. Your second problem can be a problem or an easy fix, both codes a generic for your fuel trim. I'll assume fuel lines all the way to the injectors or could be a simple filter change or even cleaning the MAF. It's doable and there a lot of guys here with the know how...they will help you and always do, just wait for the responses.
