yes, completely normal. in cold weather my wifes '04.5 takes forever to
even get "warm" and if idling it will idle all the way back till the temp
gauge looks like the truck isnt even running. we'll probably be buying her
a gas powered truck soon just so she can get some heat. my '05 warms up
quicker, but its pulling a heavy load. it will also cool down at idle.
