Mazda stalls/sputters at lights and when pulling off. Check engine light is on on 2002 Mazda Protege

Got a diagnostic code of P1250. This problem just started a few days ago about the same time the CHECK ENGINE light came on and stayed on. First I just noticed that the engine sounded rough while idling. That has advanced to the threatened or actual stalling. Nervous about driving it and would appreciate ideas. Thanks in advance!
