    Please dont gang up on me but...

    I have been told that any fault with my cylinder 4 and 02 sensor should manifest itself by the check engine light appearing??? My check engine/engine fault light has never ever come on despite having this fault for over a year now, what does that indicate??? Please don't gang up on me...
