    I have similar problems (like 3 threads down on this page) and I put on new plugs, wires, and MAF sensor and I'm still having issue. My next 2 guesses are fuel filter (20 bucks) or catalytic converter (200 bucks for a bolt in magnaflow high flow cat). I don't have a jack though so I can't get underneath the car.

    change the plug wires too, and you could have a clogged cat possibly.
