    any updates? Got p0125 on my 1997 2.7l. Changed the downstream sensor a while back, haven't changed the front. but I don't want to just throw parts at this. Had an OBD plugged in while driving and both sensors were running, not sure what the values meant tho lol.
    Engine is maintaining 183-185 degrees, coolant is full, sensor under the upper radiator hose looks clean...not sure what else to do.
