Default 87 stalling when coming to a stop

My 87 Vette is having a problem with stalling when I come to a stop. As soon as I put the clutch in while coming to a stop, the idle seems to wander then slowly die. Any ideas?

First thing I'd do is check the fuel pressure. You could have a problem with the FPR, the filter, the pump or a combination. Attach the gauge to your windshild and go for a ride, watchign the needle. You shoudl have a consistent minimum of 40ish. If at the stop, your pressure drops, you need to trace your problem.
