2001 Mercury Sable Q&A
2001 Mercury Sable Question: P0401
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. - keithA
