Well I got the scanner from Auto Zone.
The code that was tripped (twice) was P0306 which as the unit said was a cylinder 6 misfire.
Looks like I'll be checking the plug this weekend. They are less than 10k old so maybe I just got a bad one or maybe the coil is going. In any event I have a project for the weekend now.
I cleared the codes it will be interesting to see if they come back but there is definitely a stumble when cold so something must be up.
