Promo raise here? 1/2 LO8

[Dallara]

Party Poker (9 handed)

Preflop: Hero is CO with T[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/club.gif[/img], 2[img]/images/graemlins/heart.gif[/img].

Flop: 4[img]/images/graemlins/heart.gif[/img], 9[img]/images/graemlins/club.gif[/img], 4[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(5 players)</font>
SB bets, 3 call (including me), 1 fold

Turn: 8[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, BB checks, MP bets, hero?

At this point, I'm not crazy about my hand, but it has two way potential. I have the aces for high on a paired board with no straights yet possible. 2 low cards are out and I have the nut low draw.

Is this a spot where I should try to promo raise to knock out the two players behind me or is my hand too weak for that? Both players behind me are typical loose low-limit players.
