I've seen that happen in other cars, but it won't happen in our FI 
cars, because the vac adv doesn't move until the car gets up to speed 
on the highway. It won't do anything at idle or while standing in the 
driveway.

Exception: cars with vacuum adv/retard ('72 FI and european '71 dual 
carb.) On those cars the retard is active at idle.
