I imagine that the O2's in my 2002 Durango look the same, I have never changed them out and the truck has 155,000 miles on it...but no CEL and the truck runs fine....I give you props Nuke for taking that job on. I could never do that...just don't have the patience!
I blame alcohol for it actually. I had purchased the sensors some time back with the intention of swapping them out, but when I got it up on the jack stands and took inventory of just what all would be involved in getting the job done, I chickened out.
Flash forward a couple months to Saturday night, and as I was cleaning up the garage a little, I ran across a Crankshaft Position Sensor I had also previously purchased but never installed due to the amount of work required (starter has to be removed). I was fully 5 beers into a 8 pack of 18 oz cans, and as I stood there staring at the CCK sensor in my hand, and remembering the O2 sensors sitting on the shelf just beyond it, I thought to myself, "Nuke, buddy, YOU GOT THIS!
So I pulled her up onto the ramps and jacked it up onto jack stands once again, this time fully confident that I would have a fresh set of sensors installed on the car by the time I went to bed that night.
Well, I ended up passing out a little on my wheel-less creeper pad that night somewhere in the middle of the job. I came to after a while, went inside and went to sleep for real, got up the next afternoon and started in on it again. It took me all the rest of Sunday and into the wee hours of this morning to finally complete the job.
I'm glad I got it done, but I am not proud of the language I used at some points during the install. My most embarrassing string of curse words came spewing forth somewhere in the 2am-ish period Sunday night/Monday morning when I thought I had stripped out the threads on the driver's side O2 sensor bung. I won't put in print what I said to the car at that point, but I will say I accused it of fornicating with swine who had been born out of wedlock to incestual parents that should have been turned into breakfast food if there truly were a god in the sky.
Everything just kinda turned a shade of red after that, and memories actually get a little hazy from the rage I think. But when I came to this morning, the job had been completed, so I guess I figured it all out!
