Misfire is usually caused by faulty wires or spark plugs or both. Throttle position sensor failure generally causes poor response to the throttle. That is poor acceleration, slow to return to idle and rough idle.
A lot depends on when it is sputtering. Is it hesitating under acceleration? That is what happens most commonly in eclipses. It is probably a misfire in one of the cylinders. Change your plugs and wires.
