I'd guess MAF sensor or TPS sensor as a first guess.

Try unpluging the TPS and driving it for a day.

try to unplug your maf meter and see if the problem stays the same or gets worse.

CkyGuy, Dunno if you checked this out yet. Just recently i was having what seemed to be a similar problem, After checking wires, spark plugs, upping my fuel grade and adding all kinds of additives, i broke down and looked into a haynes manual. First thing on that list was "Change your fuel filter" I did that just today, and bam, car is running fine again. Feels a bit faster too. The part is cheap, here in georgia it cost only 7 bucks. It was a bit of a pain in the rear to get to but otherwise quick and easy. If you haven't yet, check that out.
