PCM & TCM need to be updated
My Jeep would vibrate between 0-5mph in gear at the beginning of acceleration, I work in a shop, and found a TSB about updating the pcm, I went to my local dealer and had them flash the pcm with the update, and the problem is no longer present!
The electronic throttel would come on off and on. Finally my mechanic told me the pcm needed a reflash/upgrade. No diagnosic showed this. It should be included in the lifetime warrenty but probably not.
