Low RPM Miss Stumble (could someone look at the datalog)

I have been having some issues with a miss/stumble. There have been no codes from this issue. The Miss/Stumble happenes below 2500rpm and is noticable when there is load on the engine. The datalog shows a short trip around the neighborhood with 2 very short highway runs. I included both the .csv file (excel) and the .atl file (autotap). Any help would me greatly appreciated.

have you tried having the car run and spraying carb cleaner and seeing if rpms change may be a vacuum leak
