I got pretty much the same thing going on my 2002 Aero, only it's more persistent, and not very jerky, more like a sine wave (well, a very irregular sine wave) kinda fluctuating up and down around 70mph, where the boost is a little shy of the yellow zone. I can actually see the boost gauge fluctuating, so I'm thinking turbo- or fuel-related. It happens maybe every other time I drive on the freeway, and sometimes it's constant during the entire freeway stint, sometimes it's gone after 3 or 4 "waves." It's around 86k mi... I bought a new fuel filter, which I was gonna save til 90k, but maybe I'll try it earlier if I can't figure it out. BTW, how do you "check" the fuel pump? I was thinking maybe it could be turbo-bypass related? Although, first things first, next chance I get I'll check the gap on the plugs...
Good luck with your issue, let us know if you figure it out! I'd appreciate any help I can get!
