Right off...sounds like a dirty fuel filter or injectors.
Dies it accelerate normally if you do a hard run, and cruise at say 50-60mph normally.

Dirty fuel injector(s)
fouled plugs
dirty MAF
failing 02 sensors can also cause some problems like that...you will not necassarily get an SES light or a code either. Usually when they actually fail you get the light. To see if they are working properly will take a real OBDII scanner that the dealers use.
