99 GA runs rough at stoplight

[99gadriver]

Sometimes when I stop at a stoplight, my car starts to run really rough and stalls on occasion. If I catch it as soon as it starts to happen and put it in neutral it doesn't stall. What would be causing this?

is this just at traffic lights, or stop signs too? !
So whats the engine size?
the idle air control valve could be sticking. A vacum leak, cloged fuel filter to name just a few things that it could be.

It doesn't always happen. I was replacing the map sensor tonight, and noticed there was a hole in the vacuum line, so I replaced that too. It's the 2.4L and I replaced the fuel filter a couple months ago.
