more problems, help!

My car shifts into all gears just fine, but if I'm in say the middle of 4th, 5th or 6th and I hammer it there is a flat spot and then it takes off? It used to just take off when I gased it, any ideas? I don't think it would be the clutch would it?

if ti's the clutch the rpm's would climb bit the speed would not, it also would likley nto catch till you let off the go pedal

these cars are drive by wire, it could be a sirty stocking tb, tb actuator or the actuator might be showing it's age
