If you have issues only at those revs then something is wrong with the O2 sensor - at those revs the air fuel mixture naturally the leanest so maybe at those ratio it reacts abnormally , causing the fuel delivery to be lower than it should so the engine is lacking power. Have the sensor tested.

Hi and welcome to FixYa!
I do suspect that you have a faulty MAF (mass air flow) sensor or bad TPS (throttle position sensor). If the car run sluggish it can be a fault of these two parts. If that's the case it will surely need replacement.
As a first course of action, I strongly suggest that you take the car in to a reputable mechanic and have an engine scan. During the diagnostic it will list the trouble codes and by then you'll know what part needs replacement. It's wiser this way than guessing.
Hope this helps and thank you for using FixYa! Have a good one!
