O2 sensor
I recently got the Jeep running code free. I had a really nasty crack in the exhaust manifold, but had no codes. I replaced the header w/ an APN today and now I am getting an O2 sensor code... code 21. Should I bite the bullet and go ahead and replace it or just pull it out, try and clean it then put it back in?

Oxygen sensors have a finite lifespan. Cleaning is not recommended.
Absolutely replace it. I recommend using NTK for your 95 XJ. That would give you the exact same sensor as what is in there now.
Tip for you. Do not, do not buy no-name "el-cheapo" sensors! Cheap parts are cheap for a reason.

4... Tear down was done pretty fast. Had to make a run to the parts store for some fuel line afterwards. The installation went somewhat smooth, w/ the exception of the bottom side bolt that goes in behind one of the primaries... had to fight w/ it for a bit.
