1. Vacuum leakage Check throttle body and intake manifold for tightness. check all vacuum hoses.
2. Faulty fuel or pump or electrical.
3. Plugged PVC valve.
4. Air filter clogged
5. Leaking head gasket.

SOURCE: ROugh idle
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.

IT SOUNDS LIKE THE IAC (IDLE AIR CONTROL) MOTOR IS BAD OR GOING BAD, BUT THE QUICK SOLUTION IS GO TO ANY AUTO ZONE,OR ADVANCE AUTO PARTS STORE, AND THEY WILL CHECK IT FOR FREE,& TELL YOU WHAT SIGNAL CODE MADE THE CHECK ENGINE LIGHT COME ON, I WOULD DO THAT JUST TO BE FOR SURE, BECAUSE THERE ARE A FEW OTHER THINGS THAT CAN CAUSE IT AS WELL,SUCH AS MAF SENSOR DIRTY,OXY SENSOR GETTING A BAD READING,ETC.

Sounds like an O2 sensor, go to An autoparts store like Schuck's, Autozone, or O'Reilys, and they will be able to a free scan for you, and tell you what your check engine light is on for. Or if it isn't on they could still tell you if it's a bad O2 sensor by reading the live data levels. Good Luck! :)
