Paid more attention to the RPM's.  THe RPM's stay low then jumps when the engine catches up and stops stuttering.  It's like losing cylinder then when the RPM's pick up it climbs to 1000 rpm and is okay after that.  No hesitation when reving the engine while in neutral.

So, here's the verdict.  It seems the spark plugs were bad.  Today it's gone and the Jeep pulls stronger as well.

I've got a PD Firewire set coming next week that I'll swap in and use my original as a backup.

Oh and with the heavy rain and winds we have had, I noticed the Jeep does still leak from somewhere.  I can't tell if it's the dash or the door.  Not really too worried about that though.  I just need to pony up and get a new door seal kit.

The only condition I've seen helped with the top end treatment (Oil, Seafoam, Mystery oil etc)
was an engine with carbon fouled rings, that had been parked. It had a lot of blow-by and using
the seafoam on it got the compression back and freed up the oil rings.  A buddy of mine that owns a wrecking yard
used Marvel oil in the cylinders and lets them soak for a day or two when he's prepping a motor to be sold that's been sitting.

You don't have to run the motor, just take the plugs out and and dump the Marvel in , about 1/4 cup each hole.
Let it sit with the plugs in for a week and then spin it with the plugs out to expel the oil. then fresh plugs, wires
and start er up. will smoke a field out till it gets warm. If you pull enough yard motors apart you find a lot with
the pistons corroded and the rings froze in them..

Carbon build up isn't usually a problem with my Jeep.  I typically rev upwards of 5000 RPM and do long road trips which keeps carbon buildup at a minimum.
