How many O2 sensors does a 3.0L Have
Guys, I'm getting ready to replace the transfer case and I have to drop some of the exhaust. I am going to replace the O2 sensors while I have it down and I need to know how many their are. I know there is one after each cat that is right off of the motor but I don't remember if there is one in front and behind the 3rd cat or not, or if it is only 1 behind it. Can anyone look and let me know. I want to get them ordered asap so I can have them here by Friday.
And FYI, I am only using the AC OE part.
