Samantha, Your idle air control valve may have excessive carbon build up on the head of the sensor and needs cleaning to ensure that it is the problem. Then replace your IAC valve and air filter.

Could be a clogged fuel filter, a bad fuel pump or clogged injectors. Need to go to the car doctor.

If the battery's charge got to low, or the battery was replaced, the vehicle may just need an idle relearn. This can be done with out a factory equivalent software by holding the gas pedal down slightly (just enough to keep the engine from stalling) for up to 10 minutes. An intake leak, MAF sensor, or dirty throttle body/idle control valve can also cause this and would need to be properly diagnosed.
