Call, don't bet out on the flop and then fold when it is one more et to you in a huge pot getting 16 to 1 this automatic, the MP3 could be raising with a smaller PP or someother crazy holding. Even if you are behind to a queen or an 8 you are 22 to 1 to catch your jack, so the implied odds on a draw are very good, seeing that you will collect more than three BB's if you do catch your boat. All together this is automatic. As ED says don't fold strong hands in big pots, on the flop for one bet.
