I did! Did new distributor caps and rotors, and it didn't help, it actually got worse after. So I did plugs and wires and it fixed it. I think it got worse because disturbing the wires to do caps and rotors probably made their already poor continuity worse. Still hunting around for a fix for an RPM drop when revving it though, but think it's just because mine has such a low idle that I should address sometime. When warm, it idles just above 500rpm in neutral, and at or below 500rpm when in drive.
