If you look at your exhaust pipe from under the truck, you will see your 02 sensor. It will be screwed into the pipe with I think 4 wires coming out of it (2 white, a grey and a black) I think it's got a 22mm nut to take it off. It can be done with a wrench (which is what I did) or you can buy a special socket that hasa cutaway for the wires. I did use the universal ones that you had to re-wire the plug onto, and it was really easy to do. you basically end up making a new plug that you put in the middle of the wires, then utilize the old plug on the end. Pretty simple, came with instructions and all. Deffinately give it a shot!

thanks 4x4kota i'll give it a try and hopefully not screw anything up

if you want to call in a project.. lol..

takes about 2 min to take it out and put it in.... the bosch ones ceom pre lubed, got them from o'reaillys for like 45-50$ each..

them charging you 90 for a diag, plus 250 for a o2 sensor is crazy! I would have told them to shuv it.

i would not have been on that dealer lot but then i do all work myself if it is at all possible
