My car use to surge a little when I first bought it, probably at 4 second
intervals. The power just wouldn't come on unless I would catch it on the
upswing, but didn't have any violent shakings....

I replaced the O2 sensor with a generic Bosch and it solved the problem to
this day and 140K later....maybe I should think about replacing it again.
