Trying to solve a rough idle problem(video inside)
Recently my 93 cherokee started having a bit of a "lump" at idle, and it's start hesitating a little bit when going from a stop in the last day or two.
I was sort of able to catch how it idles on my phone, it sits at around 600rpm and then dips really quickly and then bumps back up, feels like theres a big lump in the idle when it does that.
o2 sensors are my first thought, my protege had similar issues when it was going out and it just got worse and worse til I replaced it. Any wisdom is much appreciated!

I had a similar issue in my '96. After cleaning the Throttle body, until it looked like new, along with the IAC, it really helped a lot. I can still "feel" a very slight flutter at idle, but its so small it doesn't show up on the tac any longer.
Might give that a shot, if you haven't already.
