Throttle body alignment. I think you can leave the key on for 5 minutes or so then turn it off and start it again and it should have aligned itself. Im not sure of that though.

does the car fall over when it stumbles, to align the throttle body turn car to on position, press pedal to floor and listen for 2 minutes, then leave key in for 3 more minutes, unless you have a vagcom.

check the intake pipe from the airbox to the throttle body are the clips tight or any splits in the rubber

Check for codes.
When is the last time you changed the spark plugs?
When is the last time you used some injector cleaner (a good one like techron).
