What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[89Suburban]

I guess I am in the market for a 02 sensor bank 1 sensor 1 it threw a P0134 once and P015b 3 times on the road trip
just got back home, probably change it out in the morning when it is cool

Sorry brah

Sorry brah

ah it's not a big deal just kind of a pita to get to mostly went and got the part already $60
that's what happens when you drive around at 100mph for miles and miles
if this thing was 2wd it would be a piece of cake

Yeah, the front diff makes that O2 sensor a PIA.

going under it shortly had to catch up on work from the last 4 days, almost caught up

Well that went a hell of a lot easier than what I recall it taking last time, took a whole 5 minutes lol

fuel content was showing 55% even though I had burned all the e85 out a couple days ago, there was a pending code for the 02 sensor again and lean code for bank 2 I assume the bad bank 1 02 sensor was causing it?
cold start was a bit rough, cleared it out and reset the content, seemed to make a instantaneous difference, I guess I'll see how it starts again tomorrow while it's nice and cold again

Did you go from the top or bottom?

I drove it up on ramps and got it from the bottom, I think the trick is the angled ratchet head
