Toyota Repair: Toyota Camry 2003- AC, cell phone car charger, phone car charger

Question
My Toyota Camry EX just crossed 100,000 miles. Twice yesterday the car turned off when I turned the AC on. I was using a cell phone car charger when it happened so I thought that was it. However, it did it without the charger also. My husband check the oil and said it was not low. The Alternator was replaced last summer and I had a tune up around February 2011. It is a automatic, but I can't think of the cylinder. It is not the high speed or turbo if that helps. I'm going to take it in, but want an idea at how much money I'm looking at.

Answer
Most stalling problems at idle are caused by carbon deposits on the inside of the throttle body, I would recommend doing this first and also replace the air filter unless already replaced. Be careful, most repair places tend to oversell, if you want to you can reply and let me know what they recommend, in most cases cleaning the throttle body restores it to normal idle and cures the stalling.
