SOURCE: IDLE PROBLEM
Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue 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.

You could have a bad or contaminated Mass Air Flow (MAF) sensor. You can get a used one online for less then 100. You can also purchase a can of MAF sensor cleaner at a local auto supplies store and clean it. It located right at the air filter housing.

Not sure if this will work for you but worth a shot. I own a 2005 dodge neon. I know the ecu's are different but maybe dodge was smart and made all the cars this way. Insert you key into ignition. Turn key forward until you are at the last position right before the car starts to crank over. Repeat this for a total of three times then on your digital odometer display, you will see a set of numbers displayed. this will be your code for the malfanction(s) that set your check engine light. Like I said, it might not work on your car but give it a shot. If not, rent an obdII scanner and get your codes. Then you know where to start looking to fix your problem.
