Get a secondary o2 simulator. It does wonders.. otherwise you got in limp mode.

 

Yes, a CEL has been on for a few months, ever since I disconnected the 2nd O2 sensor....the thing is, my car's performance never changed that I know of, not until the turbo was installed.

I just found out that my Missing Link is broken. Could this have been part of the problem? I was told the MAP sensor could see up to 5 psi...and that's where I'm at. So it could be a combo of the 2nd O2 sensor gone, and the Missing Link?
