What is the engine rpms when this happens? I know mine has a shudder when sitting parked now and again. When it happens the tach shows rpms are down aroun 500 and when smooths out it bumps up a bit to closer to 525.

Hi Chad
Thanks for reply
Yes sounds about right we had same issue
Especially on cold start
Shudder and drive little while
It's gone on D mode
But back on P randomly when rpm is at 500

It isnt anything i am concerned about as some vehicles have a lower idle speed than others so unless it starts stalling when its idling like that i will leave it be.
