I have a 93 mustang lx.....its a 2.3 with a automatic transmission. I can start the car fine an it will idle fine in park. If i put the car in drive or reverse then it will die. Its like the torque converter is locked up or something. It feels like having a manual car an putting in first without using the clutch, just die

 

Something is definitely wrong. Have you made sure the vacuum line is connected?
