Yes plastic does not do so well in the cold. This is why I chose to wait rather than force the issue because the hood release handle is plastic and last winter it snapped off. Things get stiff and I could tell It was going to brake if I pushed my luck. I could have boosted the car and got it going but this way I am not trying to get another release handle shipped across the pond.
Every couple of months Franklin idles rough and has no power. I think this is some sort of "limp home" mode. We just shut him off and restart again and all is good. Happened again yesterday in the middle of Sandra's mail run. Not sure the cause but it goes away on it's own... so far.
Still -30 this morning but the forecast is for more moderate temperatures in 4 more days.
