Just to update my original thread,
I picked up my car last night. She is running silky smooth now even when cold. Let it warm up completely before rolling into the throttle a few times to make sure all was working as it should. Very happy with my dearlships investigation, diagnosis, and action.
I would've had the car Monday morning but I was busy and wasn't able to pick up the car until last night.
Couldn't be happier!
