wow I remember my crx doing that with my old d15b1.. anyways my fuel relay and the dizzys rotor and coil had a lot to do with it granted the engine was about cooked by then.. but I'd check there first on the coil which I know autozone can test to make life easy and not do it yourself. Also, is the ecu throwing any codes?

One other thing..plug wires, my mustang had the worst problems with idle wacked out out till i replaced those, would those happen to be the original? Not saying that they would be the cause but if they are aged and brittle could have something to do with it along with a fuel filter checking.. either way if in doubt on the fuel filter change it out anyways their cheap insurance of future problems.

All I have for ideas that are easy to check out and shouldn't cost ya anything to get that coil checked rest of them you can inspect for yourself but again ecu codes would be best if any are being thrown.
