My check engine light has been going on and off for over 3mnths now and i finally went to Auto Zone today to figure it out. I own a 98 contour svt, and i believe the code number was 1131: Lack of Ho2 sensor? I am hoping that the Ho2 sensor will be the fix, however i need to know where that sensor is located in the engine? Does anybody know where it is, if so is it hard to install/replace?
Thanks,
Marty
