Why is my car running so lean all of a sudden!??!
Ok, quick set-up review:
b18b t3/04e 57 trim
DSM injectors including afc hack, w/ resistor box.
Recently My o2 sensor bung blew out, and I didn't know about it for about a day. After finding this, I drove w/ the bent and mangled o2 sensor (from hitting the ground) for about another day, just to get it to a friends place to weld in another bung. The o2 sensor was scrapped, for another good one that was laying around-- we believe that it was from a D series motor. We welded the bung in, and re attached the new o2 sensor. While doing so, i was working on my friends resistor box wiring so i check my wiring to make sure I was doing it correctly. When i removed the black tape from the wiring, one of soldered wires came off, so I wrapped it around (quick fix) and re-taped it.
Later that night, my car started stuttering around 2 to 3grand. I believed this to be a plug problem, maybe I fouled out my plugs. I checked my plugs this evening and OH MY GOD-- they are WHITE and burnt, and by the threads, they are black. I have no idea how this happened, i've been boosted for around 2 months now, and every time I've checked my plugs, they were a beautiful caramel color--- a little on the rich side. Please help me in my insight to what happened to change!! Is it the new o2 sensor, the old one?

???
Could it be from the Resistor Box wiring??
Also, sometimes at idle, my revs bobble up and down very quickly for about 5-10 secs, then stops and goes to normal.
