Like stated, lately I've been noticing more and more that at about 1/2 to 3/4 throttle my acceleration is been fairly choppy. At WOT I'm strong, and the I'm good for when I use little throttle. BTW I've got 80k mi, with 15k on wires, about 20k on opti, and new pcv, plugs, air, oil, and fuel filters. Thanks for any help.

Pull, clean and check the movement of the EGR. Chances are it's sticking. Replace the gasket while your there.
