Looking at past year DEQ reports they seem to change every two year? I read two sensors are in front on Cadillac converter and two more on the other side, four all together. Oh, my check engine light works but does not stay on when started, or running. I don't know what else I don't have the money for mechanic, my wife that is unemployed teacher due to budget cuts, two teenagers, not lot to go on any help would be great full
