Question
mark i changed the 02 sensor and the check ingine light still on can you tell me how to get the ligt out.and can you tell me to riset the services ligth to.thanks mikenwjke

Answer
  Mike, let me just hand you a loaded gun. VBG You have not told me what code was set or why you chose to replace the O2. Who's advice are you listening to? The parts guy? Oh yeah, he makes a living selling parts.
  Scan the vehicle and  get back to me. Also note any changes in behaviour. I will try to help you. (Hey doctor, why does it hurt when I do this?) Smile.
