My suggestion would be to check the idle speed spec and see if it is actually dipping below the min spec.

My guess is that it isn't.

Can you post a snapshot of the concern occurring?
Make sure to flag the problem when it occurs.

Do you have any accessories on the vehicle?

Where are you located?
