Why would there be occasional hesitation with acceleration?

There have been a few problems with this vehicle, but the most recent is after obtaining a new battery the vehicle's lights and the sound from the radio, along with the speedometer would "pulse" at certain times. Not any particular thing would instigate it, or make it stop. Then after a few months it started having issues with acceleration usually after a particularly bad case of the "pulsing". It would do it once, or 10 times, then eventually "catch" and drive normally. I thought it seemed like an oxygen sensor, however it seems to be closely related to the "pulsing" so now I don't know what it could be.

Do you
have the same problem?

I would have the alternator tested and make sure the battery cables are clean and tight.

The alternator was tested when the battery was, and then after the battery was replaced and it is fine. The cables are like brand new, the only other issue with the battery was the ground wire needed to be tightened which a mechanic that did some other work told me he did.
