I noticed the other day after driving to work and not needing to go inside the building right away I sat in my car and was listening to the music. I had my A/C on and when I had the car in park. I noticed the engine was sputtering/shuttering. I wasn't sure what was going on. Today, when I got home from work and parked my car the A/C was on and my car immediately started to sputter/shutter again. I turned the A/C off and it stopped. I turned it back on and it started up again. I have no clue what is causing this problem. I attempted to search for answers online to see if anyone else was experiencing this same issue but I got no results. Can someone tell me what could be the problem?

 

Could just need a reflash at the dealer. Sounds as if the PCM is not bumping up the idle when the compressor is engaged.
