It might be to do with throttle fully closed "learned position".
In PCV software/tools there is a facility for resetting the closed position. It involves opening the throttle fully with the engine running (scary).
Also if you have altered the TPS setting the ECU can need to learn the new throttle closed position. Some do not think this is necessary, but I do it first using the Healtech OBD tool.then reset the PCV afterwards.
Then again I might be barking up the wrong tree altogether as I am no expert.
