key dance was: 1 2 pause 5 5.
This was after re-connecting battery negative cable and then ALSO after taking a short spin.
Have not located codes book.
The spin was not conclusive about bucking.
The engine stalled three times while warming up. I had wanted a clean ride after re-connecting the battery... to replicate when I had both computers out last week.
I did get up a hill pretty easily, but there might have been some bucking.
I did not have wallet with me, the garage door was open and there is no exhaust system, so I hesitated to give it a longer test run.
But I got the codes, so that is a start.
