Any problems associated with 02 sensor won't appear until the car has warmed up a little. One way is the car will buck a little like a bad fuel delivery.

Sounds like the sensor is bad, although they are pretty durable. Get one out of a junkyard or donor car and see what happens.

How about the fuel pump? That's pretty common.

Check the lift pump in the tank for proper operation too! Do you hear the fuel pump when pumping? Does it sound like bees in your fuel line? Thats a sure sign its on its way out!!
