Check for any codes in the memory, if there are some then address those and see if the stumble goes away. Sometimes a live data scan can pickup on things that are just slightly out of specs but not enough to set a trouble light. Some other things to do would be to check coil output, clean the injectors professionally if it has never been done, make sure you have proper fuel pressure and flow. HTH
