91 3.1 rough idle then dies

Car starts, runs like missing, dies out. Also dies if you open the throttle. Showed map sensor code, replaced map sensor, didn't fix it. Fixed a vacum leak, still does it. What else can I try?

Use an ohm meter and check your plug wires. They should be appx. 1/2 scale. They sell a small screw driver with a light bulb in it at parts stores. Slide this past the wire cover for the spark plugs. Make sure your coils are firing.
Advance or Auto Zone will check the module under the coils free if you take it in to the store.
