Default check engine light problem

My check engine light keeps coming on. The problem codes are po1128 and po1130. My thinking was that the mass air sensor was bad , so I replace it with a new one three days ago. No change, the light continues to reappear, and the codes remain the same. Can anybody guide me in the right direction?

Did you physically clear the CEL light with a scan tool?

If so, then look for vacuum leaks or fuel pressure issues.
