The warning cluster problem (i.e., clock resets itself to 1:00 or stays off) is most likely just the cold solder joint issues common to most FC electronic accessories - no relation to your engine problem, but it be could be a factor in why the CEL isn't always displaying errors.
Simple fix involves removing the cluster and resoldering the larger solder connections between the circuit board and the one connector plug. I did this when I first bought my '7 (over 10 years ago) and haven't seen that problem since. There's was a good "how to" article for this procedure with pictures on the web, but the link I had to it on my PC now returns a "page not found".
