Was there a code? befor you changed the o2 sensor? or is there a code now?

Well it could be a number of things fuel,spark,air sensor...does it do it all the time? or only at idel?

Use a long screwdriver or prybar to listen to each cylinder and to each injector. Place one end on what you want to listen to and the other end to your ear. This is a pretty reliable way to track down a miss.

I had a miss on my '95 2.5L I couldn't find, and it turned out to be a bad crank position sensor (CPS).

also check the TPS... Mine acted up once, and it was a bad connection here. You will also want to check the ignition (rotor and cap would be a good place to start).
