To overcome this problem during long idle periods, the engine must run at a fast idle, especially in cold weather, to keep the engine temperature up.

I, like everyone would like to know what "Excessive Idling" means and we all relate this to time. I believe that TGR has some good information; wherein a cold engine could contribute to fouling injectors and more.
This would then mean that excessive idling is more a problem when the engine is cold. I know that it takes forever for my engine to get off the "C" mark when starting cold. When operating, the engine temperature is around 192 degrees. It would be interesting to find out after being up to 192 degrees, if low speed idling brings the temp. down and how fast! What are your thoughts?
