Try some octane boost. if that dose not help it can be your Fuel pump, one of your spark plugs, or a coil pack. the idling up and down can also mean bad timing i would have your car looked at but you can try the above first
SOURCE: car wont idle at all
ok idle valve is playing up small device on your throttle body that controls you idle look up on web or here is a link were you will see it

SOURCE: car keeps cutting out while in idle
it would help to know alittle bit about the car like make, model, year, and type of engine.
SOURCE: Car is not idling. Need to keep foot on the gas pedal to start.
Hi there,
there is a screw(situated in a hole) on the throttle body and this can be adjusted to increase the rpm. anticlock to raise the rpm.
SOURCE: engine will not idle will cut off as soon as foot is off peadle
possible solution, there is an idle circuit on your mass airflow sensor that allows air to bypass the throttle plate. if this little actuator is not working then no idle air will be able to get by the throttle plate which then tells the mass air flow sensor that there is no air moving which in turn tells the computer to stop pumping gas into the cylinders...which make your car shut off. hope this helps, cheers

My car is a 2003 Mitsubishi eclipse 5spd 4cyl, People tell me its bad gas, but I've had the gas since friday 6/15/12. Yesterday it did the same thing, but a few time it didn't cut off, it kept idling up and down sitting at the light or stop sign.
