We did our own splicing of wires to extend the passenger side O2 hook up.i wonder if the computer is reading to much resistance or something.We were very careful in cutting and soldering and shrink tubing.We did use the same gage wire.I also did use some foil tape to protect even further the wires.
Hmmmm

well im assuming since you know your LTFTs you are logging some how right? If so, you can check what fuel trim cell you are in.

Well I just went out and cleaned the 2 passenger side O2's.They both had a little black soot on them.Then I switched them front to back.
No more funny numbers on bank 2.They all go to zero at WOT.
Now time to set my enrichment and go from thier.
Thanks for your input.
Hope this clears things up.
