I'm glad that worked for you! Word to the wise, pay attention to the coolant temp gauge, do not let it overheat or you run the risk of cracking the cylinder head. I mention that because it'll eventually show a cylinder 3-5 misfire code.
The CEL will usually stay for several days of driving unless manually cleared by a code reader or unhooking the battery.
Silly question, but have you checked the spark plug? Compare it to one of the others and see if it's worn out or if the gap is out of spec. If you get a code reader, you could switch the plug to a different cylinder to see if it changes. Might be the fuel injector, too... see if the 1st plug has a coating of fuel on it that the other plugs do not... could point to a stuck injector. Or, if that one cylinder is noticeably burnt maybe no fuel at all. The condition of the spark plug can tell you a lot.
Have the codes checked to see what the exact issue is... might be a different code than the first time and give more clues.
I've got a code reader that you could use. I'm in Newark, down by the University.

Did any of the plugs look different than the others?
Wiring is a pain to track down... Could be a short, bad flasher module or even the turn signal lever (multi-function switch). The most common cause is the flasher relay... It's a small black box behind the kickpanel near the brake pedal. Bad wiring is a close second, start with the drivers side tail light, it gets boogered there due to trailer harness wiring. If the relay doesn't fix it, and all wiring is good, then the turn signal lever is the last place to check.
The flasher relay is available at pep boys and other places, but there are a few different ones so you should remove yours and take it in with you to compare.
I spoke too soon, the CEL is back! 
kind of lost as to what it could be at this point. anyone know of trustworthy mechanics in the newark area that specialize in jeeps?
If the multi function switch is similiar to the one on the wrangler than autozone has it and its relativily cheap. Mine was having a similiar issue with the hazards sticking and that turned into the left hand turn signal sticking, that was what fixed it. Id try the relay first though because its probably less money and more accesible.
The cps censor shouldent create an actual misfire. It feels like it but its just the cps cutting the fuel pump. If your getting an actual misfire code I doubt its cps related.
Have you changed your plug wires? You might have a worn out one thats not sending to the plug. Mine got a miss with an engine light and rough idle when one of the wires wore out. It also coded a misfire in a particular cylinder like your getting.
Does it run rough when the misfire happens and is it mainly when first starting the Jeep after sitting for a few minutes? There is a problem called "heat soak", where heat coming up from the exhaust manifold will literally turn the fuel in the rail to vapor (gas) and won't have the right fuel/air mix in the cylinder causing it to run pretty rough and misfire codes. You haven't mentioned anything like that, but worth a try to ask... I "fixed" it with my old Jeep by putting in hood vents to clear the heat, but there are a few methods.
