I pulled three codes form my car after getting Check VSC warning with check engine light on - P0012, P0171 and P1170 Anyone have same problem? ANy thoughts or ideas?

What is your question?

Dash warnings were going off and on for about three weeks. On for a day or day and a half then off for a week or so, then back on the off. Now on forthree straight days. Had the codes read as stated above. Just looking for some thoughts or ideas.

What makes this problem better or worse?

no noticable issues
