idle drops car dies

[stanics]

87 Stock turbo auto. When I drive the car it runs great, except sometimes when I let off the gas on the highway it backfires through the exhaust. When i come to a stop the idle sometimes goes from 600 ish to next to 0 back up and then down and back up and then down a couple of times, at this point it will either shut off or even out at normal idle.:wtf:
Any help ideas??????
