1994 Honda Accord MAP Sensor

I went to the Auto Wreckers the other day and retrieved 2 MAP Sensors.
I installed the first one it failed, I installed the second one it didn't resolve the problem either.
It's hard to believe that both sensors were defective, perhaps it's something else all together. What could it be?
My car continues to stall upon rapid decelleration(sp) and usually at the worst possible time, the middle of an intersection!
I was wondering, maybe it's an electrical problem, is the socket that connects to the sensor mal-functioning, possibly blowing the MAP sensor up every time I install a new one, I'd hate to purchase a new MAP sensor ($87) then destroy it by connecting it to the exsisting circuit.

Please Help Me, I'm so frusturated!
