I remember reading that it's possible to swap newer for older distributors, provided you swap the positions of 2 of the wires that go to that 3 wire connector. But I can't remember which ones.
I've got a 94 too. I hope replacing the disty fixes the problem. And I hope you stick around this board, because you know stuff, there's so few of us left nowadays. There used to be such a big MX6/626/Probe community, but ProbeTalk.com is dead, and 626.net is very quiet.
