Not holding idle

[RXtacy]

Ok, new revelations. I went back to the car today to take another look. When I first put the key to on I got a PIM voltage of 4.85 and it was highlighted. The values read as follows:
PIM 4.85
VTA1 .52
VTA2 1.11
VMOP .91
WTRT 2.28
AIRT 2.23
FUEL 3.82
O2S .01
I then pushed the pedal to the floor and
PIM 4.98
VTA1 4.39
VTA2 4.97
Everything else stayed the same. So I turned the car back to off, and checked out the MAP sensor, it seemed to be plugged in correctly, but I unplugged the wiring connector and reattached. I then went back and turned the key to on. Now the PIM read 3.32 and was no longer highlighted. I tried to start the car. I started and reved freer then before (would rev past 3k) but was still very lumpy and pouring smoke out the tail pipe. I held it at 3k rpms for a while thinking it might just be deposits built up from sitting and it would clear out. Continually smoked, but after would hold idle between 100-600 rpms. It would vibrate and smoke incessantly the entire time it was running. I have no idea what is going on at this point?
