Chaotic

I drive a 2006 Chevy Aveo and recently got the clutch replaced. After leaving the shop the check engine light came on. I took the car to the auto parts store to get it checked out. The error code was something to the effect of a problem with an O2 sensor. My friend and I looked under the hood and saw that there was a plug that he said was a vacuum (something or other) that had come unplugged. He plugged it back in and we got the error code removed thinking that the problem was resolved. It apparently was, for the time being, because the light didn't come back on for about three or so weeks. When it did come on it went off and on while I was driving. Seemingly at random intervals. There was no apparent problem until just recently. My car has stalled a few times while decelerating and is a little sluggish or 'jumpy' while accelerating.
What could it be? I changed the oil because it was a little past due (to no avail). I do need new spark plugs and wires but I am not sure that is the problem. My car has 49.000 miles and has been in and out of the shop since the first year I had it.
Also...
(I have the powertrain warranty but I'm not sure if this will be covered. Especially since I do not posses all of the receipts for the oil and oil changes that have been performed on the car. Anyone know anything about this?)
I didn't replace the O2 sensor. My mechanic friend assumed since there was nothing actually sounding or feeling bad in the car initially that it was a downstream sensor. He said that would simply make it use more gas than it should. He told me upstream was a little different but I didn't get a chance to ask him what else it could do.
