Did you finish the install?? I did OBX headers and exhaust (no CATS) and i am having issues with my left side O-2 sensors. The check engine light is on. It says left side sensors are not reading. Got any helpful ideas?

Haven't started yet, just trying to get "My ducks in a row" so thing go smoothly. Did you have any problems with the threads for the sensors? Did you have to cut the tunnel plate?

The installer had to re located the position of the O2 sensor because it was hitting something. The exhaust shop re-welded it and the rotated it slightly so it would not hit the "bottom plate"?? Anyway $60.00 later all is well. The check engine light is irritating me to death!!!
