P0401 on 2001 Mercury Sable

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Car has 42000 miles. Check engine light comes on while driving. A slight chuging sensation comes shortly befor light. Replaced control solenoid & cleaned EGR valve w/carb cleaner (no help). Could a bad sensor cause engine to chug? Should I consider trying to clean port @ intake manifold? Any other ideas. Thanks for the help.
