Wow, sorry I didn't read your first post until now.

Your symptoms are caused by a bad IAC (Idle Air Control) Valve.

"The throttle body has an air control passage that
provides air for the engine at idle (the throttle plate
is closed). The IAC motor pintle protrudes into the
air control passage and regulates air flow
through it. Based on various sensor inputs, the
powertrain control module (PCM) adjusts engine idle
speed by moving the IAC motor pintle in and out of
the air control passage. The IAC motor is positioned
when the ignition key is turned to the On position."


With that said, the problem with you IAC, when you turn the key the pintle is not moving out of the hole to allow air to get by to start the jeep, and when you push on the gas pedal it allow air to get into the engine and then after a few seconds the IAC opens and allows it to idle.

I had this same exact problem about a year ago, I replaced my IAC Valve and it took care of the problem, REMEMBER TO DISCONNECT THE BATTERY BEFORE REMOVING/REPLACING THE IDLE AIR CONTROL VALVE.

you must disconnect the battery or you will not get any change, when I first replaced mine it didn't help still was doing the same thing, so I figured it was abad part from autozone, well took it back and got a new one, and when I was removing it I remembered that I forgot to disconnect the battery before replacing the last one, so I made sure to disconnect the battery this time and I have not had a problem since.
