I've had the exact problem (with a 4.0 jeep, even) and ended up with condensation in the distributor cap causing it to run poorly. Open it up and take a look for any moisture and let it completely dry out before reassembling.
This is what WD40 is REALLY for.
Water Displacement, Formula 40 works like it was made for this job.
Weird, right?
One of these oughta fix it.
For those of you who said "internal engine issue," take a bow. So, yeah, anyone got a spare 4.0 Jeep engine?
How bent is said rod?
or rods
Wow. So when you said swimming you really meant swimming. Straight to the deep end. I tried the same thing twice when I was about 4. My mom put me in swimming lessons soon after
Poor jeep. I'm always a little sad when a Jeep dies.
I think it's more of a hole than a bend. It sounds like what was bent may have made said hole.

"Well hell, when I was in the service, I had a CJ with the old 258 I6 and bought an AMC 360 to swap in, and we run that sumbitch with no oil in it for over 387 days straight trying to kill it until it had 1/4" of play in the rod bearings and it clattered like an old diesel, but hell if it didn't keep running that way until we run out of gas to put in it and got bored watching it."

<Takes bow>
Same thing happens to the ricer kids who run cold air intakes under their cars.
Significant water puddle--->gulp of water---->daddy buys junior a new engine.
Spare 4.0? I think you mean suitable V8 to swap in

We discussed that. For her first engine swap, sounds like she'd like to keep it plug and play. But it was discussed....
Nice thing about Wranglers if you already own one is they're never really not worth fixing unless it's destroyed from top to bottom.
I guess she went a little deeper than i was thinking. Usually the only liquid a 4.0 airbox fills up with is oil from blowby! 
Ohhhh I want to be first to say LS swap time!!!!

Cousin Eddie must have been looking over my shoulder when my son reported his car quit after driving thru the puddle.... Also learned not to buy a short block that was sitting in the corner of somebody's shop.... buy a running vehicle to pull the motor out of...
Sorry to hear the Jeep didn’t survive...

I was always on the mechanic end, doing the engine replacement work. And the customer usually had me install the stock intake system while doing the engine R&R. Those factory engineers were pretty smart when they built the car in the first place.

Well it took until 2018, but we finally have determined who the U boat commander is.

And I even have it on Vid The water was 1/3 up the doors. When I put the camera down in the middle was when I realized this was worse than I thought. Oh and I was directed into the water by the police. That was why I pulled out my phone and recorded it.
DAng, that blows. We used to have an old 92 Geo Tracker my wife bought new before we were married. Once it was long past Daily use we used to go off roading with it. My wife drowned it in a large puddle/pit, to the point the vehicle was floating, all 4 wheels off the bottom. I was back at camp, but she had both girls and her dad in the car. She pulled the perfect cute blond trick, stood up, waved her arms in the air and called help. Not surprisingly she soon had three Jeeps come to her rescue. By now the vehicle had sunk to the bottom (water came part way up the doors). They pulled her out, pulled her plugs for her and turned it over to blow the water out. She limped back to camp, I went to the local Wallyworld to buy oil, filter and a pan and changed it there and then. One sump full of oil plus one small lake equals approx. 5 gallons of chocolate milk, but I filled it up with fresh oil and drove it 200 miles home while sat on folded towels but I still got soaked. I changed the oil again at home and the car ran fine for another 5 years until rust (accelerated by the water and sand from sinking I assume) ate into it to the point I yanked the rear seat belt mounts out of the floor with a good hard tug. It then went to the happy off road park in the sky.
I would have thought a Jeep could have stood up to being drowned just as well.
I have a free 99 4.0 with a few chunks of piston skirt missing, other than that It ran great when pulled. So it's more of a core without a vented block as they say in the 4.0 world.
My plan was to put some pistons in it that don't suck then wait for the next broken Jeep to come along. Then I realized that I have enough projects.
The difference is that your Geo probably didn't suck water down while running. I suspect she turned it off when the Tracker lost contact with the ground, then it settled to the bottom and ingested water.
It's when you suck in water and then try to compress it. High school physics here, liquid doesn't like to do that. Something has to give. If you're lucky, the car just stalls. If you're not, the rods give. The speed at which the engine is going when the water comes in is probably a factor.

No pictures of the carnage? :)

It's a big one! I've never heard of an engine that hydrolocked at idle having a bent rod. But it figures that most people are still trying to move when they suck water.
I remember during one typical S. Texas flash flood, i was standing in the transmission shop i used to work at watching cars trying to ford the river in front of the shop. A lowered Mustang was pushing very gently through at low rpm and stalled. Couldn't get it restarted, and since he was in front of a shop he and whatever passengers pushed it in. We pulled the plugs, cranked the motor, put the plugs back in and it drove off sounding fine.
In reply to David S. Wallens :
Experience.. bad experience.
I love the way you make that sound like it's just your average day. Flash flood, stalled car, quick water drain, send them on their way
I do not have much personal experience with hydrolocking cars with water. Done it with fuel, though.
