I had a similar problem with a 1996 JGC. It was a clog in the air conditioning condensate drain.
Your jeep is much newer, I would think they would have addressed the problem by now, but maybe not.

Response to my original posting and what was done to the Jeep GC. The code never re-appeared but the fuel pump was changed with a manufacturer defect. That was changed out with a good fuel pump the very next day. Also, I had the fuel pump regulator that made the original troubles go away. The Jeep starts and drives good now. Just a bit of shaking at a stop and an existing rattle noise under the car (maybe the convertor cover). Otherwise all is okay for now. Thanks for the input you provided to me.

I have a 97.
If you haven't done so, make sure the throttle is clean, especially the cylinder where the piston travels. I don't know why, but you need a "tamper-proof" torx bit to disassemble the throttle so you can clean it
I have rough idle and it almost stalls. Replacing my evap purge solenoid solved the stall problem.
Try disconnecting the vacuum line from maninfold to evap purge solenoid. It's for emission control. See haynes manual for more info. Plug the fitting on the manifold. Disconnect wire from the solenoid so that engine computer cannot enable it or plug the line. Disconnecting wire may cause a "check engine" light.
If you have problem in Park, you can do it in your garage with hood open. If not, make your road test as short as possible.
Make sure engine has warmed up. The engine computer won't enable the solenoid until it warms up
If it runs better, replace the solenoid and any vacuum hose that looks dry or rotted. My almost stall problem went away.
Note: If you do this yourself don't make my mistake. It's easy to pull the line off the canister which means the canister is evaporating all the time and is not controlled by the solenoid. The canister is under the bumper. You have to remove the air filter housing to access it and even then it is difficult.

I am going to take a wild guess. Excuse me if I am way off.
The line that drains condensation from your air conditioner has become partially or completely plugged so the water backs up and eventually has to go somewhere.
Run your air conditioner on a hot muggy day at least 30 minutes and see how much water comes dripping out underneath the car. The drain should be close to the a/c coil that is integrated with your air ducts on the dash. It should be clear water if the drain is not dirty. No water is an obvious indication.
Take it to a shop if it looks suspicious. I never did this one. I believe you need compressed air to clean the line.

This is same 97 JGC i posted before, 4.0L I6....The story continues but has taken a turn....All vacuum issues resolved....Engine still idles rough but with a very consistent vibration. All the chopping is gone.
Did compression test...Bingo!...All the cylinders were 145-150 psi except cylinder 2. It usually peaked at 120. Squirted in some oil. Went to 150 like the other ones.
Spending big $ on engine a problem because I will need it for transmission....Local shops don't want to do repairs...They want to swap for used engine....Swaps have a much better $/effort ratio...Nobody wants to scrape a gasket anymore...They might replace my 160K engine with a 140K engine.
Is repairing engines a secret nobody wants to get out?
If we can put a man on the moon, we can repair a cylinder.
What are my options ? What tools will I need ? What is best approach ? What suppliers are rated best ?
Thanks for any input.

could have compression ring frozen in ring land
i would try and get some SEA FOAM from pep boys checker and squirt some in the cyl and let soak for a while then run it some for a few days with some in crank case then change oil see if dont get better small price to pay if works as if you didnt over heat the bugger could be stuck from carbon deposits and sea foam should take care of that

The air conditioner in my 96 Jeep Grand Cherokee is not working properly. When I add freon, all of it is gone within 3 weeks. I know I have a leak somewhere but my mechanic has been unable to find it. Also, the floor board on the passenger side used to get soaking wet whenever I ran the air. Has anyone else had this problem and how can it be resolved?

I can't help you with the freon leak, but I also have a 1996 JGC that had the wet passenger side floor.
I just posted this link a few messages back(#4155):

take to ac man they have a freon detector should be able to find leak

I have a 97 and I have Chrysler shop manual for it.
1. The wet floor board is probably due to the drain line being plugged at the condenser. I believe you need compressed air to clean the line. I've never done that repair.
SAFETY GOGGLES A MUST TO WORK ON PRESSURIZED A/C SYSTEM.
2. If any of the fittings use O-Rings, find them and replace the O-rings. After 12 years of engine heat they are in less than perfect condition. You might have to buy a special disconnect tool (not big $). But there is risk of breaking a fitting when you work on it yourself.
3. The Chrysler manual says put the vehicle where there is no wind, evacuate freon, recharge and use "electronic R-134A" leak detector", whatever that is.
Auto a/c work is difficult for diy. I hope it's a line leak and not the compressor.
96 thru 98 were the best years.
