You'll need to get this looked at by an experienced mechanic, these engine light problems are complex and take special diagnostic skills to fix, it's almost never as simple as pulling diagnostic codes and replacing parts, as you're finding out. I suggest finding a smog station that is a "Blue Shield" repair shop.
