Loaded my emissions tune, got 4 codes. :(

Alright, its the O2 sensor. I flipped them from side to side and the codes changed to P0161 and P2272. The sensor has probably been dead for a while but I wouldn't have known it since I've been running an after-market tune for years.
Ordered up a new motorcraft sensor and will solder it up when it arrives.

Great news. Brenspeed is pretty good with their emissions tunes. Those were the same codes (stuck lean/heater circuit malfunction) my truck was throwing when an O2 was bad so I knew one of them had to be the problem. Glad you got it working.
