Car stalls when idling and A/C is on

[Matt Timion]

Any ideas why my car might stall when I idle and have the A/C on? It's been doing this for a year, but I rarely use A/C.

It all started when I had my headgasket changed last year and they adjusted my timing.

We were driving onthe freeway yesterday and I threw it into nuetral to coast for a bit. i didn't expect my car to stall on the freeway, but it happened. I had a little panic attack for a second, but then I just decided to bump start the car.

What would cause this to happen? The idle just goes so low that the car stalls, and the A/C isthe culprit!
