I recently threw an ses light on my 04 GT, it was for something else but the other codes that were in it said that for all 4 of my 02 sensors that there is a heater circuit malfunction and now and then it will say that they are stuck lean I cleared the codes but they keep coming back up. Im running a catless X-pipe with MIL eliminators in the back, is this caused by that or is something screwed up here? :SNSign:
