If you can, drive it to a repair shop where they can take a quick peek at it. Or, you can try to upload a photo. I suspect / hope the engine will not stall if you put your finger on it slowly. The Engine Computer pulses an unusual type of motor to various positions to control air flow at idle to control idle speed. A vacuum leak adds too much air to the engine so the computer closes that air control passage. When you plug that leak, since the throttle position sensor is not moving, the computer isn't expecting to see a change in engine speed. The sudden drop in speed catches the computer by surprise. It pulses the Automatic Idle Speed (AIS) motor to increase air flow, but the motor can't respond fast enough, so the engine stalls.
