The hesitation at high RPM is sounding like a possible fuel delivery issue. Change your fuel & air filters (clean the air filter if you have a K&N).
Over the next few weeks when you have a little maintenance cash, read over the "common problems" section for cleaning your MAF sensor and
Throttle Body . There is a good how to on changing your plugs as well. The Duratec is quite particular about what plugs you use.
By this time, you'll have read & learned a lot about your car. Having maintained it, you'll feel the performance & handling at its best, and you will learn to love the Contique.
