NORMAL.
If this continues for more than a few minutes after starting-- not normal.
Yes, in most cases but if it is extremely cold out, the grids will start cycling again if the truck is stopped and idling - even if it has been running hard for hours and is at full operating temps. It may also go to a high idle under those conditions.
Wow. The good news is that we have never been in cold enough conditions to have that happen.
So-- disclaimer: No idea what happens in well below freezing conditions, as that is when we head SOUTH.
