Default Engine Dies at Idle with AC on.

Usually after the engine has been running for a while and its really hot out the engine dies when sitting at a traffic light with the AC on.
What's the most likely cause?
This problem just started on Friday.

Is this the stock ECU?

I'd be looking for vacuum leaks.

Hell I wish My A/C did anything when I turn it on.

If it's MS, maybe you have to adjust the idleup and duty cycle. If stock ECU, then the above as mentioned. Might be grabbing unmetered air from a leak and leaning out as it tries to compensate

Okay, I'll check for a vacuum leak because I'm still using the stock ECU.
