I had similar problems on my ex-girl fiends Civic. I replaced all kinds of shit. And then a friend of mine just happened to have the same thing to his Accord. And he finally took it to a shop after replacing the wires, plugs, o2 sensor, distributor etc. And it turned out to be the coolant temp sensor on the side of the head. It was like a 60 dollar sensor. But you'd be surprised how that thing will make your car run like a POS. But her car would bog down really bad as well, But that fixed it. Hopefully that helps if you continue to have that problem.
