Hi everyone in New here I have a 1986 camaro irocz with a 305 tpi auto. Overall the car runs pretty good my problem is when the car warms up and you come to a stop light it runs rough and stalls if you don't out your foot on the gas and bring it up to 1000 rpm or so. But it fires right up again. if you put it in park it does the same thing it runs rough and stalls. But ounce your moving its fine what could cause this to happen

 

What I'd try first:
