New here and need a little advice. Going to replace both sensors 2004 GC 4L fed config. Can both be accessed from under the vehicle? Connector for pre-cat really behind the engine? Hard to get at? Jeep is at cabin so taking tools to do it there. just looking for a little advice. Thanks
Welcome to the garage.
Can´t tell you much on the change itself, but did you buy new sensors already? If not, go for original Mopar or Denso. Bosch sensors are good quality, but they heat slower then the Denso´s and could give you a fault code.
