Cold weather has arrived here (-8c, 17F). Last night I had the truck plugged in for about 2.5 hours before start. Started fine, slightly high idle, slightly loud. But today after sitting 9hrs in the blowing cold UNPLUGGED, when it started, there was no high idle, just 650rpm, a little loud yes but not as loud as other "warmer" days (maybe around +8c, 46F) where I've seen it high idle at almost 1000rpm.
My question is that why does the high idle not happen when its really cold? I would assume that the colder it is, the more likely I am to get a high idle.
Also, it sounded like the batteries were struggling a bit, but it still turned over in a timely fashion. The batteries are only 6 months old(but they are made and I bought them in Mexico, covered in dust) and all my grounds are clean. Normal sounding? I'm running 15w40.
But more importantly, where is my high idle?
