Engine Performance problem
2000 Mercury Sable 6 cyl Front Wheel Drive Automatic 82000 miles

Idles TERRIBLY. Auto Zone trouble codes P1132, P1152, P0174, P0171, P0401. I have replaced the EGR valve, with no change. What would be the next logical step?
Also analyzed by newest portable diagnostic computer from Mac Tools, the Taskmaster. It did a full diagnostic, even checking the power steering pressure, and at one point did something in the diagnostic that made the engine run noticeably better - almost normal. But when it was finished, it basically came back with the same information that was displayed be the care computer codes listed above.
Can you help?
