Engine running really bad, missing, sputtering

[85begalttype]

Drove around town today was running good, came home and decided to unplug orange wire to reset computer (bad idea) , plugged it back in and now you have to floor gas peddle to start it and misses and sputters and idles at 2000rpm, runs really really rich. tried letting it idle for a while to see if the computer would re-learn things and correct itself, but that doesnt work. could maybe my maf is done for?

its a stock 85 t-type and i already replaced the maf 2 months ago
