1992 Honda Prelude EGR valve

I own a 1992 honda prelude 2.3 DOHC. On occasion while excelerating in any gear the engine feels like its being bogged down I lose speed then all of a sudden it rapidly picks up speed like a valve or something oped up and I take off. I already redid my exhaust from my cat back and my O2 sensor. Only thing left I can think of is my EGR vavle. Is there somethiing else that can cause this. I have no engine lights on. And this happens at any speed any gear I can be cruising on the highway at 65 and be fine this happens. When it happens in a lower gear such as 1-2 it spudder and then just take off.
