Chris,

What you describe sounds like a fuel shortage problem, actually I have heard of your problem several times and it has always been related to the in tank pre-pump failing. Does your car have a pre-pump? I think they started using them in 1984 so I'm not sure if a 1983 would have one. Be sure your air sensor has free movement - check and/or remove the metal screen on top of the fuel distributor venturi to insure it doesn't restrict air sensor movement. good luck
