Change your O2's you have a heated O2 and once warmed up if its reading incorrectly, Guess what wrong air/fuel ration and studder

 

The o2 sensor will warm up in about 45 seconds, much before the car will warm up. It will also make the car run a little richer, not misfire.

Do you have any check engine lights?
