ANOTHER XT6 Question

[Darksied-X]

Okay, so the XT6 has not been the ideal commuter car. It been running okay for the past 2 weeks, but its really showing it's age. The main thing that concerns me now is it seems to have a problem with the fuel system. At highway speeds, the car seems to hesitate and lose power about every 1-2 miles. Just giving it a little gas doesn't do anything, I need to floor it to get it going again. I don't really know if this is damaging the engine, but it's annoying as hell when you drive 150mi a day. It was doing this to me last winter, too, and a new fuel filter cured the problem, but that didn't work this time. It seems speed more than temp is related, because it does it worse the faster I go. Just driving around town, it doesn't even do anything. Anyone have any ideas? I'm thinking about selling it, and I don't like pawing my problems on other people. I'm gonna post this one on the XT6 site tonite when I get home too, but I can use all the help I can get. Thanks.
