Default 1985 corvette computer problem

I shut off the car and it was running ok, but while it sat the battery when dead and when I got it started its been running terrible, rich mixture, missing, when you get under power it starts to spit and sputter...any suggestions on how to get it back running right?

The 85 needs a fully charged battery. If you jump started it, that may be your problem. I would test the battery to see that you have at least 12 volts. If no, then disconnect the negative cable and charge the battery.

If you do have 12 volts at the battery then ...test for trouble codes.
