Recently replaced headgasket - Now car is sluggish and gets 25% less MPG- Any Ideas?

Ok, I have a Jetta GL 2.0 (1997) with about 105K miles. Recently the head gasket started to leak so I pulled the head and had it completely rebuilt, then replaced the head gasket and put it all back together. The car cranked up and ran GREAT - but - There is a little bit of a stutter at low rpms when you first take off or shift gears (it is a 5 Speed) and it feels just a little sluggish. It is also getting 25% to 30% less MPG than before. The plugs are new and correctly gapped, the Rotor button is new, Distributor cap is new, Timing is set correctly - and Triple checked. Any one have an idea of what to look for or where to start with trouble shooting?

thanks!

Did you replace the coolant temp sensor? Sounds like it may be bad, also did the car run hot before the HG change
