check the hose going to the mapp sensor could be crushed ,dilapidated etc. also check idle air control valve and do a throttle body cleaning, if this does not fix your problem you may have a problem with the torque converter/torque converter clutch solenoid.

I own 2 90 Luminas and both have the same Problem when the battery goes dead
I need to take one right now to the dealer to get the computer reset and that will fix the problem
I have learned to change the battery while the car is running and the ALT. with out disconnecting the battery
