O2 precat, #8 misfire, clock spring or something like that. Was told its in the steering wheel an distributes power.
Changed cap, rotor, and wires. Disconnected battery and went for a ride. Still have slight hesitation, but a HUGE improvement. O2 sensor still stuck...I'm sure changing it will help with the hesitation. Needed new wires anyways and I'm glad I checked the cap. I replaced it last year with el cheapos, not knowing any better, all contacts were corroded. Needless to say, she runs damn well now. A2ny suggestions on what else I should do? Thanks!

Those could be indicating a big ugly expense -- if your plenum was throwing oil into the chambers and clogged the cat after fouling the oxygen sensor, a #8 misfire is common and a sign of a cracked head. Time for compression/leakdown tests to find out.
If your oxygen sensor is still the one you couldn't get out, you're going to have to get it swapped out somehow. Running around with a failed pre-cat O2 is hard on the engine and costly at the gas pump, too.

Yeah, post cat O2s are basically nuisance CELS but pre-cats are a big deal. PCM relies on info from that for mix, timing, etc. Get that one changed out.
As for the misfire on #8, yep I'm afraid that's an indicator of a head issue either with the gasket or an actual cracked head.
Clock springs are cheap but they are a PIA to replace and you need a steering wheel puller. Last one I did was in a 2002 Grand Cherokee, took me most of a day...
