Update -- Stumble Problem Solved??

I *think* I figured out the stumble problem on my 89 900t (LH 2.4)(http://www.saabnet.com/tsn/bb/900/index.html?bID=236419)
Previously, I hadn't been able to recreate the stumble with no load. But it was bucking *hard* yesterday (soon after throwing in another coil) so I stopped by the side of the road to mess with things underhood. I was then able to re-produce the miss, so I held the rpm steady with a pliers @ the throttle and played around with the wiring a bit while the car stumbled.
@ one point, I pulled the rubber boot off the Hall Sensor plug (square-type) to inspect it (connections looked fine), pushed/tugged on the three connectors at the back of the plug, & re-installed. I also pulled the sheath around the three wires up closer toward the plug.
No more miss. So far.
The thing that sucks is that I have messed with the Hall sensor wiring a million times & couldn't get the car to miss before. I also shielded/grounded it w/aluminum foil at one point without success.
Anyway, Van, LM, et al., try pulling the plug, gently peeling back the hood, and messing with the connectors. Even though they may *look* good, they may not be good enough. Or maybe just tugging on the sheath a bit did it--who knows??
If I don't get the miss after a few more days, I'm going to pull the plug again, cut off a bit of the wiring & re-attach the pins just to be, well, anal-retentive about it.
Thanks all for the suggestions...
