High Speed Accelleration...

[pbmain@xxxx]

I'm going through some of these old messages, but haven't found 
something quite like this... (again, new owner here, so don't shoot..)

After some city driving for about 15 minutes, I've taken the car out 
on the interstate, been up around 80MPH (Typical commute speed in 
Detroit) for another 15 minutes, then go to change lanes to let 
someone by. I go to speed back up, and it doesn't want to go...the 
speed just falls. Luckily, not a fast deacceleration or below an 
acceptable "highway speedy"...but I give it gas and I hear a change 
in pitch like it's downshifting, but it don't want to go above 55-65 
or so. 

I need to do some 0-60 timings to see where exactly things are in 
that respect, which may point to some other issues since it seems 
quite slow overall in the acceleration category, but not to a huge 
extreme - just seems to others like I don't feel like pushing the 
car. The car is a low mileage 3 speed. Starts fine all the time - 
hot or cold conditions, seems a bit too rich at initial startup, 
until about 2 minutes pass and something "clicks" (cold start valve?)
and it idles very smoothly...

Any tips on any of this is appreciated :)
