AQo hand that really bothers me

[Grease]

Borgata 6/12 from a while ago. I have thought about this hand a lot, and can't make up my mind about it. I think there are some mistakes here, but I'm not sure where.

The two limpers are very loose, but can be aggressive from time to time.

The PFR is fairly tight, but has loosened up since he hasn't won a pot in a few hours. He may be on the verge of tilt. He is short stacked and has 3.5 bets left.

Two loose players do what they do best, PFR does what he does best, I make it 3 (very debatable), blinds fold, limpers call, PFR mutters (my image is strong, I think) and calls.

All check to me, I bet, all call.

Same as before, PFR is all in

I bet, both players with chips behind them fold.

Thanks for the imput.
