I recently found that my 2001 4.0 warms up much faster and puts out good heat when I hold it to 2000 - 2200 RPM for about 6 to 7 minutes at a cold start. Question: how much extra gas would it be using then?
I feel it is best to warm petroleum fluids slowly . When the engine runs, power steering, and Automatic transmission fluid are also warmed by internal friction . After a minute or two, your ready to roll . Not to argue, but your procedure isn't best for the car . PS Have you ever seen a warmer car ? Takes a bit to warm up, interior stays warm all day .
Depends upon the ambient temperature. I'd let the thing do its own idle down to curb idle(it is on pre-programmed warm-up strategy), generally speaking only a minute or so.
Then it's okay to add throttle when the vehicle is not moving but again, don't turn on the heat! Remember your heater core is it mini radiator, let the engine heat itself up until gauge moves, then turn the heat on.
