You got something wet (obviously). Check under the distributor cap for moisture, pull the plug wires and coil wire and put some of that electrical grease in there to keep water out. If it's none of these, and your Jeep is running fine, disconnect the battery for a while to reset the computer and see if it dried out. If it is running rough, keep checking all your electrical connections. Where is the computer on that thing, could it have gotten wet? I'm no 12 volt guru, but I think these would be good places to start.

disconnect the battery for a while to reset the computer

I think I've said this a million times now, but this method DOES NOT work on OBD-II computer systems ('96-up) as they have non-violate memory. You MUST use a scanner or correct the problem to clear the codes and or memory.

Also, sounds like you got water in the distributor or ignition coil, or posibly the computer wiring harness. One time I got code 43 and it went off after a day of driving (apparently the problem had fixed itself.)

[TwistedCU]

The middle wire from your distributor cap ends on top of it

easy to fix?
