Sounds like PCM or ECU is failing. Either to reprogram or replace it. Before I went to take it in for the recall, it was fine except for silly P0300, just one. After they reprogrammed with "appropriate software" my pcm kept throwing P0300, P0131, P0132, then P1129. I went HUH??? I shouldn't trust the Jeep dealership service center.
