Default 1998 Frontier King Cab dtc P1448

First post. Glad to be aboard. Located in Middle TN near Nashville. Received dtc P1448 along with generic P0440. The P0440 is simply stated Emissions problem. The P1448 code for the 4cyl engine defines as "Vacuum cut valve" Does anyone have any ideas as to what to look for? Thanks a million!
