I did a search and found nothing about this topic. I seen some write ups for ls400, but arent of any help since the sensors are in different positions. I can unplug the harness, but don;t know what tool to use to take off the actual sensor. I tried an o2 sensor tool, but it was not deep enough (only 2.5 inch deep). It would not reach the actual hex to get a grip. Anyone know what tool to use? 7/8 wrench?

 

nevermind...it is finished!
