Look what I found (while doing tune up)

So I started going through the Jeep to make sure I am able to squeeze all the gas mileage I can out of it for my move to WA. So I change the plugs/coil as I wrap that up I notice that my 02 sensor harness is resting on the exhaust manifold (my fault for not routing it the right way after changing out the manifold) This is what it looked like wonder if the sensor was even working Jeep runs fine but burns lots of gas, thats why I am going through it. Anyway I cut out the burnt section and spliced it back together, weird thing is I never got a CEL.

Now that you found that the CEL will come on, don't ask me why but that's just how it works...
