Just unhooking the vacuum to the transmission only rules out the vacuum as the cause of the stall. It still could be other issues with the transmission or torque converter, but not likely. The idea behind putting the dwell meter on is to see if it shuts off when the bog/stall happens, thus indicating that you are loosing spark. You should try raising the idle speed to say 1000 rpm's, then see if it bogs/stalls out when hitting the brakes hard. One last thing that comes to my mind is the condition of the fuel supply hose from the tank, have you checked it for cracks? I wonder if the pickup in the gas tank is loose or has something blocking it off? Some of the ideas are long shots but keep digging until you find it. Good Luck, Don
