Just a really dumb question

My 98 Dak has over 150K miles on it and I still have
the original O2 sensors in there. The truck has had a
tune up within the last 5K miles but now I'm noticing
a bit of a stumble on acceleration, and my gas mileage
has been slowly decreasing. No Check Engine lights
have illuminated, but I'm wondering, could those old
O2 sensors be causing this? Or is it just old age
getting to the truck and something I need to learn to
live with till I get a bona fide problem identified by
the PCM?
