Hello, My mechanic told me that the code for the check engine light comes up as a faulty oxygen sensor. I have also been told that it is a really easy job. I'm handy with tools and whatnot, but I have not tackled this particular job before. Could someone direct me to a site (if there is one) that lists the steps involved? Thanks. Much appreciated! 1997 Accent, 4 cyl, automatic. AGB
