Misfire Cylinder 1, then random misfires

Hi
I have been trying to get this misfire problem fixed for months. First it was misfire cylinder 1. We did a tune up. New plugs, wires, distributor cap and rotor. Worked good for about a week. Replaced fuel filter. Put sea foam in gas. Still misfire, some rough idle at times, misfires going 70 mph too. Got a code for ignitor failing. We replaced that. Next got more misfires cylinder 1 and multiple misfires. Engine warning light would flash at times. Took it in again, garage told me misfire happened at 650 rpm on cylinder 1 on that code. Next time I had code show up, they told me catalytic convertor. We replaced catalytic convertor and O2 sensor. Worked good for about 6 wks, now misfire cylinder 1 and random misfires again.
Please help! I drive 63 miles one way to work and need this car!

What year and trim level (EX, LX, etc) is this Civic?

Some years had known issues covered by TSBs from Honda.
