Last night on the way home car shut off when we are at a traffic light, when we turn the A/C on car shuts off as well. It never happened when we first got the car. We cleaned the IAC valve but still the same. Check & refilled fluids are also still the same! MAF sensor probably could be the issue but can please some one give a good advice or opinion?

I would replace the IAC valve and clean the throttle bore as well as check for vacuum leaks.

Here are guides and diagrams below to help you fix the problem:

The idle air control valve can get frozen and not work no matter how clean it is. Let me know what happens.
