After fixing all of my boost leaks my car was running great, then after 1 day i started it up it runs super rich and has this light on.

After searching through the forums I found and will try the following
  1. Test voltage of wires going into MAF
  2. Try a different MAF (I have an extra one from my old talon)
  3. Check the wire going into ECU port 90
Questions
  1. Could a valve cover gasket cause this? My valve cover gasket is leaking and due for a replacement.
  2. I have the narrowband simulation running for my wideband. Could this cause the issue?
    1. EDIT: I'm going to turn off narrowband simulation, I don't need this because I am running a front o2 sensor. This might be why my car is running funny now.
  3. My o2 sensor never comes out of open loop, I am trying to figure out why.
