Have you tried this:

Throttle body reset procedure

Step 1: Turn the Jeep to the "on" position but not the engine running position. Step 2: Wait for all of the dummy lights to turn off (check engine light will stay on). Step 3: Depress the accelerator REALLY slowly...Driving Miss Daisy with a touch of Cocoon slowly...all the way to the floor...
