Sounds like a BAD MAF sensor!
The MAF Heats the volume of Air,the Incoming Air Temp is measured,and
a signal is sent to The PCU for Air/Fuel control.

When you jump on the Gas pedal,is the car a little slow to react?

Wide open Throttle = Colder Air,the IACT sensor drops more voltage going to the PCU.
Closed throttle = Warmer Air,the IACT sensor drops less voltage going to the PCU.

Rob has a very good point!
Fuel filter,Air Filter,Air Box,and throttle body cleaning.
MAF sensor cleaner can be bought @ local parts store.
