I wanted to add some more information since I have spent a LOT of time reading the old posts on similar problems. The idle is low, and a bit rough, but does not "hunt" up and down in rpm as others have experienced. I hope this helps.

Can anyone help me with interpreting the codes 2,5,and 11 from pin 14?

Thanks,

Experience is something you don't get until just after you need it.
