Re: NC oxygen sensor after cat problem
It's worth at least checking that the extension cable is wired properly -- I got one that was mis-wired from the factory, and it took forever to even look. Once I checked, the problem was obvious. The check is easy. Just plug the two ends of the extension cable together, and look at the color code on the wires coming out of the plugs. Each mating contact should have the same wire color on both plugs -- if it doesn't, return it.
