After the car heat, the water temperature at 80 degrees total, 90 have not been to read, but the high idle about 150 rpm, 700 rpm in the past, now more cold weather idling higher, now turn around at 850, but significantly higher fuel consumption
Water temperature is low cost oil is certainly the easiest way is with a hard shell to block part of the warming effect of the radiator well as for how much you want to try to stop. Idle temperatures will rise up relatively low. What is the pull speed? Not run fast but continues to run uninterrupted some time. Usually two hours can be. Is to allow the engine to reach full swell purpose. Such a shift is to be based on the vehicle speed and the reference engine speed. Not based on the engine speed. Driving is probably the single 30 towards third gear, fourth gear towards forty, fifty five-speed ahead. Many people on the car ahead of change. As long as the engine sounds smooth, no trailer can be.

One thing is to leave the IAC adjustment alone, you have a vachum leake betweent the mais air flow sensor or a intake leak.

I just solved this problem on my truck after fighting with it for 2 yrs. Mine is the 5.0 though, check your PVC valve and replace if it is bad. After that Take off your IAC and spray down with carb or brake cleaner and scrape all the carbon build up out of it and work the spring inside. you gotta really clean it out though! After that if it's opening and closing easily put it back together and it should work! you might have to adjust the idle a bit to get it all the way. But after doing this my truck went from a 2000 rpm idle down to about a 700! I hope this helps you!!
SOURCE: no heat on idle approx 700 rpm but lots of heat
When the engine is cold,remove the radiator cap and make sure it is full,check fluid level in reserve tank too.
