In this specific hand I would fold.
After the flop you have MPGK.
Your outs - TcTs - probably good
K gives you 2 pair but completes possible str8s and possible flush - those are tainted outs.

You also have to take into account that you are 4:1 to hit your outs on the turn or the river, but you do not see those 2 cards for $2. First of all if there are 5 people in the pot then 2 can act after you and raise you, but even if they fold on the turn you will probably have to pay $4 to a $20 or $24 pot with 10% of hitting you outs, even if you assume 5 outs
