Have you run an OBDII scan yet? If you get a P0170 code, it means the Mass Airflow Sensor is dirty. Very common and easy to fix.Remove the MAS and spray the daylights of out it with Quick Dry Electric contact leaner. (CRC is a really good one) If the code comes back shortlly after clearing, the MAS is bad. I'm going through this right now and awaiting anew MAS. (PS the MAS is in the tube directly after the aircleaner.)
