Don't think it's a bent wheel, the tire store did not say anything about that, and it is not a reproduce-able event every time.
The engine has recently had a little roughness at idle and during slow driving.
Another friend suggested that if the ignition system is failing, and it's dropping a cylinder or two, it could certainly create enough vibration to give that feeling., That, coupled with the other comments above, leads me to think it may be ignition/spark/ etc related.
We'll see what the dealership comes up with, I think it would be "less of two evils" if it is the ignition vs front end, just because I was planning to do a plugs and wires replacment anyway as part of a tune up. Hoping to avoide the coil and ICM, but if that's the cure then thats the price of 32 year old electronics and wires and plugs !
Fingers (and credit card) crossed !
