a clogged fuel filter could be the culprit, or a faulty o2 sensor. i am going through this EXACT problem with my h22 accord, just started doing this yesterday. i replaced the fuel filter and nothing changed. i think it's my o2 sensor.

BTW, my tps is also out of volt range, and the problems it gives is iratic idle after warm up sometimes it evens out and then it will just start idling crazy again...up and down.
