I have a 2013 R/T Classic 5.7 - looking for help wondered if anyone else has encountered same problem. Either with or without cruise sometimes when it begins to climb a grade it's like engine just momentarily shuts off and for a few seconds nothing press it to the floor nothing then it launches itself (if cruise is on) for a couple seconds pauses again then really launches back up to set speed then settles down n goes on .. without cruise just have to keep throttling until it decides it's over its temper tantrum lol. Otherwise runs smooth as silk? Only on a grade - cruise or not- sport mode or not- day or night - and sometimes it wont do it at all????
