I'll monitor the Voltage display during this event. I have noticed that once coolant temps get up to normal, they stay there -- and TC lockup is aggressive (finally) -- even in outdoor temps 10-15F ambient. I also altered the air intake to draw from the engine compartment for Winter. FE hasn't dropped a whole lot, which is a shocker.

Another hypothesis is a knock sensor of sorts, but I don't think it's equipped as such. IATs aren't high enough either.

Honestly, the only inconvenience is a slight drop in power (especially on hills), which has to eat into the FE bottom line. Aside from that, I'm picky about vehicle operation and the slightest abnormalities. It's so faint, a non-hypermiler may not even notice it unless you monitor the numbers and feel closely for the vehicle's nuances. I just want to better understand the operation. The biggest obvious problem is a leaky valve cover gasket (stinky burning oil underhood) and lack of transmission maintenance. Christmas to New Years = little work in my field, finally! Time for maintenance. And the cold temps are perfect working conditions (better than the heat, IMHO).
