Hi! I strongly suggest that you open the hood and remove the positive battery connector then let it sit for atleast 10mins. to reset the system. After 10mins. reconnect the positive battery connector turn the engine on and see how it goes. Hope this helps and thank you for using FixYa!
I cracked the owner's manual to read about the mysterious red light. I
learned that it was the Electronic Throttle Control (ETC) warning
light. The manual reads: "If a problem is detected while the engine is
running, the light will either stay on or flash depending on the nature
of the problem."
The manual's recommended solution? "Cycle the ignition key when the vehicle is safely and completely stopped."
It worked. After "rebooting" the Jeep, the ETC and stability control
lights didn't come back on, and the Jeep's engine was back to
normal.
What is worse to me is owner's manual solution of "Cycle the ignition
key when the vehicle is safely and completely stopped." That means
Jeeps expects this problem to happen from time to time. This problem typically has occured for me when I have hit the brakes and
held the throttle at the same time. If the Jeep is not in 4 wheel
drive it screws with the ESP. The Throttle stays in "safe mode" until
you cycle the key. This has hapened to me when driving vehicles in a
parade.
There was a recall for unexpected power cut off in Wranglers. The TIPM may need reprogrammed.
Keep us updated.
I quote here the steps you need to follow:
1. Find an unused section of road with a good spot to pull-off/turn-around.
2. Pull off of the road and shut your car off.
3. Turn your key to the "On" position (but don't start the car), and wait for the 'idiot' lights to go out.
4. Press down on the accelerator, and let it back up.
5. Turn your car off.
6. Re-start your car and cruise up and down the road testing your throttle responsiveness.
Depending on how fast/slow you do the 4th step, your throttle will either become more or less sensitive/responsive.
Repeat steps #1 through #5 as needed until you're satisfied that your throttle response is as good as it's going to get.
Remember these things 'learn' how you drive so if you drive like Grandma for a few days, it's adjusts accordingly.

If the vehicle has electronic throttle control and a dead battery, do not jump-start the vehicle. The electronic throttle control light will come on after a jump start because the programming in the electronic throttle control computer can get corrupted by the high voltage and current of a jump start.
Often, the electronic throttle control light will come on after a jump start and the vehicle performance will deteriorate over time, until it becomes un drivable. When an electronic throttle control vehicle has a dead battery from say, leaving the headlights on, it is recommended to have a slow or medium charge with the key out of the ignition. This will let the computers gather their energy slowly without being shocked back to life.
The computers in a modern vehicle are somewhat active, even when the key is out and the engine is off.
I think you will need re flashing your computer once...
