2009 pontiac G3. sputtering in gear. new clutch or slave cylinder? on 2009 Pontiac G3

I have a 2009 pontiac G3. It is sputtering and putting in gear. Shifts fine and clutch feels the same as always but its sputters in gear and then takes off. Slave cylinder maybe? Clutch?

basics, basics. how are the plugs?? how long has it been since you serviced???

it has a recall on the plugs. Waiting for GM to get the parts. Could that be the issue?
