Message Left bank O2 sensor at idle is reading high while the right bank is low. There is your problem..

That would indicate a T-Body balance problem.. Or some other Non Balanced air leak ( PCV or Vac line Off ) That is likely where your Stumble is coming from..

I have not messes with a Running '96 before, so I'm not any real help on the Procedure for T-Body or Idle adjustment.. But check the PCV's and hoses.. Fuel Regulator Vac Hoses, and see if you can locate a leak..
