Also, if it was that far advanced I'd disconnect the distributor vacuum line and see if the timing changes (it shouldn't on an '87 Milano.) If it does it's possible someone adjusted the idle with the throttle plate rather than the idle bypass, such that you're getting ported vacuum to the distributor at idle (which, again, you shouldn't.) If that's the case you've seriously retarded your static timing, which would explain the sluggishness.
Just trying to think of reasons it would be that far advanced at idle.
