there are 2 things that usually cause this, one is a dirty intake idle control valve and the other is hard engine mounts, I would say that both most likely apply to your car. try cleaning the intake with the following procedure from Ford.
Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Mercury had a recall on 3.0 duratech motors in 2000 and 2001. If you get a fuel smell at startup then you might have a bad lower intake gasket, it could cause a miss if seal is cracked. Article No. 01-4-3 you can get it on AllData.
Also, check the PC rubber L piece that runs from the PVC valve to under the throttle control - it could be busted.
Make sure ignition wires are not cracked. If you haven't tuned it up in over 30-40K consider doing that.

A scanner reading- P0171 system too lean bank 1 code is the MAF sensor.
The MAF sensor should be replaced. It is a fairly easy fix and relatively inexpensive. If you are running too lean on one bank, it is more than likely the MAF.
Let me know if this helps and if not I will try to help you farther.

Did you have battery disconnected or dead recently?
Try to place ignition in run without starting engine for 3 minutes (shut off all accessories and lights etc..). Then shut it off and then start it. Should relearn the idle.
If this doesn't fix the problem, unplug the MAF sensor, if it runs fine with it unplugged, its the MAF sensor.
Exactly what happened on my wife's 01'.
