However unlikely it may be,it could be a bad ECM.I've seen it before,not on a Jeep,but it happens. They can go haywire and just throw random codes. I would replace the CPS also.

I've done it before. Not on a Jeep,but if you can remove it easily take a large prybar and knock all the crap out of it.

I don't know codes. But i'm guessing it's a misfire,since you were messing with the plugs.
