My test drive got put off until Thurs Morning. I will update when I have more...

Spent some time on the way home from work tonight to analyze and characterize the issue...

Always happens from first to second, and second to third.
Sometimes when the IMA kicks in it can cause it.

Always during acceleration, whether hard or gentle, and the miss aproximates the level of acceleration, the harder the acceleration, the harder the miss. If I stomp on it, I can hear a loud audible pop from under the hood.

Not bad for a caar with less than 700 miles eh?
