Rolling Idle
What you are describing sounds like a rolling idle. A symptom of the vehicle running too rich. In the days of carburators, one of the tuning tricks was to richen the idle metering mixture screws until the car starts to "roll" then back off the mixture screws a turn or two.
Try to get your PFC tuned, then turn on the closed loop function.
