What did you do to your TJ today?

Couldn't find the "what i'll do to my TJ tomorrow" forum so I'll ask here.
Code P0158. And i did see where I'm to replace 1,3 or 4 O2 sensors. I'm a 2002 with the 4.0. How many am I replacing please. And must use NGK
 
Went scouting for trash in the woods in preparation for an Earth Day weekend cleanup...hosed off the Jeep and more WD-40 in the speedo sensor plug to displace water from snow wheeling over the weekend...and tightened a couple of retaining bolts on the track bar and rear control arms.

I'm glad you got it out! But, man, it hurt to watch that... :)
I realize that I didn’t post it here, but the seat latches were already broken from the PO putting it in. I thought it was just stuck when I first posted today, but they were mangled beyond help. I only resorted to yanking and cutting once I realized it was broken. I didn’t just destroy a perfect seat.
 
Spent the weekend chasing a few possiblities for a P0303 code. New spark plugs gapped at .040 and properly toqued smoothed out the idle and starting. I noticed that my power steering line is leaking right onto the connector and O2 sensor below it. Bought some electronics cleaner and power steering stop leak to see if that might clear up some more.

I've also been having an intermittent issue with the Jeep stalling when coming to a stop, so I bought a tool to check my fuel pressure, but got the unlucky draw and my fuel rail does not have the shcraeder valve. I've been searching, but I'm not having much luck seeing how to hook it up. Should I just do the fuel rail swap to the schraeder equipped fuel rail?

Also have evap codes P0442, P0455, P0456, and P1494. Going to assume that much vacuum leak isn't helping anything run smooth either.

You can buy a hose that has a schrader valve on it. Unhook the lines and put the hose in place. I don’t think it’s meant to be permanent though. Can’t remember where I got mine, but I can look when I get home.

Probably could make one for cheaper than I paid for mine if you know what to buy, which I’m sure some on here do.

I don’t remember where I got this. Somewhere online. I just got it thinking it would be good to have on hand if I ever need to check mine. Someone here probably knows what you’d need to make your own.

A 2002 4.0L should have 4 O2 sensors. 2 for each bank of manifold cat convertors.
