I don't know of any other Civic VX concern that is so littered with confusion, misinformation and outright fraud than that of O2 sensor replacement. Call me a cynic but, as tempting as it may be, I cannot find much support for jmf's no-name $99.99 unit. "Worked fine" is relative. Simply unplug your malfunctioning (or functioning, for that matter) sensor and your Civic will "work fine" too. If you're willing to tolerate a potential 40% (!) drop in efficiency.
A quick search shows that we have many, many threads on the subject without any definitive results or recommendations. Only wish I had the time to become the authority on this subject. Any member with sufficient personal experience willing to weigh in?
