JK - Thanks for making yourself available this week for me to swing by. As fate would have it, there was a lengthy delay at the marina, followed by a low hanging telephone wire about two miles down the road that wasted alot of time in my day.
On the way home across WI, I only had two codes set, even though the temperatures were in the 90s. Both were shortly after getting underway, after sitting still and idling.
Heat soak and hot fuel is my hypothesis.
We'll keep trying to connect and test this thing!
