Default Mass air conversion problems

I recently did a maf conversion on my 88 lx (computer, sensor and pigtail) and i've got a doozy. when the car is cold it runs super rich and the idle surges, much like the o2 sensors are totally screwed, and it pours out the white smoke. when it warms up it runs fine, no problems at all. at first i thought it was just the computer learning the fuel curve, but after three days of this i'm at a loss. i have cleaned the maf sensor. if anyone has had anything like this happen before i am more than open to suggestions. HELP!!!

to be honest i'm not 100 percent sure what it came out of, i bought it at a mustang salvage yard and the guy said it was for a mass air mustang, he sold it as a "kit" type deal.
