A carburetor has a choke, but ALL Jeep 2.5L Wranglers are Fuel Injected from the factory. They do not have a choke. Something is amiss with his sensors, I would check the air intake temperature and coolant temperature sensors to see if they are functioning properly.
Pushing the pedal to WOT activates a circuit in the computer system that forces the injection system into a preset value.
