Sounds like the symptoms of a vacuum leak. Use Vise-Grips to block off air to the brake booster and HVAC systems. Inspect all other vacuum lines to the EGR valve, BAP sensor (I’m not sure the ’93′s have those), the EGR VSS (on the driver’s side of the front cylinder head), and the carbon canister (driver side of vehicle, on frame rail behind the splash guard).
Also check that every cylinder is firing. Start the engine only when it is dead cold, and let it run for maybe 20 or 30 seconds, then shut it off. Touch each runner of both exhaust manifolds. If any feel cold to the touch, then it’s not firing. I’m assuming you have a 3.8: it’s very important to know the rotation of the rotor. It’s very easy to install the plug wires in reverse order, or make a mistake, and the engine will still run.

If you have a carburator, you will need to rebuild or replace it. If you have fuel injection, it sounds like your injectors are stopped up. Running rough and missfiring can be the carb. or fuel inject. but it can also be a case of bad timming. The timing may just need to be adjusted. Take a 1/2 wrench and loosen the distribitor and turn it one way for only a small 1/4" at a time. Make sure to mark where the distribitor is befor you start this process. You may need to put it back where it was.
If turning it one way makes it worse, then go the other way until it is better, worse, or no different.
Hope this helps.
