Its probably your cat. Was your check engine light on when you took it? I would assume not but im just being sure. Every time any of us have had high readings in nox its been the cat. Buy a new one, you could probably get a universal one and have a muffler shop weld it on for like 40 to 50 bones. <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/kewl.gif" alt="" />
