Throttle Body problem?

[1993CivicVX]

I've done all the tune up bits. You don't think the o2 sensor would make it run smoother at highway speeds and accelerating? It's just these sudden surges of power (small) but annoying--make it hard to maintain a constant speed. Losing and gaining power all the time. Especially at higher speeds. Is this just part of the behavior of the lean burn? Do you think replacing the throttle body would help? I still haven't done any of the other DYI mentioned on here by various members.

I replaced my O2 sensor last year because I didn't know how old it was. I didn't see any difference with the new one.
