the idle air control actuator is a common problem in this type of fuel injection an is mounted in the throttle body also the map sensor should be on top of intake make sure is connected right and have full vacum if so just tap on it with engine running and will miss if it is faulty please let me know if this helped or need further assistance i'll be glad to help.
check to see if one of the injectors is pouring more gas than the other while idiling. if one of them is check the wires going to it to see if there is a short. if not the injector is probably junk.
i want you to get OBD trouble codes from your computer. then post them on here. im sure it will hold clues to what the problem is...Various auto part stores will do this service for free in hopes you will buy parts from them...but call them first and make sure. parts to look at Idle Air Control (IAC) Valve...it acts like a choke with modern engines. also the Coolant temp sensor is associated with this as well. Second is the Mass Air Flow (MAF) Sensor. and last one is your Manifold Absolute Pressure (MAP) Sensor . lastly it could be the Throttle position sensor (TPS).. all these can be detected on your computer within the car. although the the numbered codes will be labeled with abreviations like MAP Sensor or IAC valve. also you can manually test all these sensors at home with a regular voltage tester and reading some online info...just search " How to test a MAP sensor" almost all sensors have very similar readings from car to car, so its pretty generic. hope this helps
