I have had a similar problem for a year. (its been haunting me). Tried replacing so many parts: dizzy, injectors. wires, plugs, ect sensor, fuel puimp, fuel pressure regulator, the list goes on. It was always less worse during the winter. But my symptoms were hesitation during acceleration, like it would feel jerky while giving consistent throttle. I just got done cleaning my EGR (there was a lot of carbon inside and formed around the part that opens the diaphram. Its safe to say, it fixed my problem.
