loss of power

Earlier on today i was accelerating in 2nd gear slowly when the power went then came back on a split second later ,it happened twice today, but it is the first time it has happened in two years of ownership,and when i scanned with my sts it came up with p3073,not too sure what that is but also throttle response wasn't right ,when sitting at a steady speed and then accelerating it didn't feel quite right ,but since i cleared the code it seems to be ok,any ideas or suggestions would be great,thanks .
