twice last week when temps bottomed out at -20F, I had the following symptom
when I started up the following morning: the engine cranked, fired up, and
idled normally. However, when I engaged drive and pressed the accelerator to
go, the engine rpm did not advance beyond 2000. The accelerator pedal was
functional, but I could press it to the floor and engine rpm did not increase
the least little bit. This symptom persisted whether in D, R, or neutral. I
had just enough (2000) rpm to idle back in the garage. I let it idle for
10 minutes (closed garage door) where I suppose the temp got up to around 0
degrees. After 10 minutes idleing (warming up) in the garage, then the symptom
disappeared completely and everything was normal.

What's up with that ?
