i pulled the wire out of the connector to the CD for the tach/speed relay. at first it ran much much better. then i cold notice the miss in the 3k rpm range as i kept driving. then it got to where it was doing it in the 2k range. with the wire removed, for about 20seconds, the tach bounced up and down from 0 to about 2500. i had noticed it move about 200 rpm's once or twice before, so i checked the output of the alt, 14volts. i think i will put my MM on the battery and set it for record and drive around and see what it picks up.

this seems to be heat related too. when cold, it does not do it but it does not take long for it to start under normal conditions. (part of the reason i thought fuel/mixture related).
