o2 level is zero, what reading is this? High HC is unburned fuel or a rich mixture (as you have indicated). NOx can be caused by a LEAN (hot) combustion situation. I think we need to cure the high HC first. Once this is in line, if the NOx is still high (and we have no vacuum leaks) it may require a neq catalytic. The AMM is probrably not the problem. I am sure it is still under warrantee.
