Excessive Idle Time can Cause Poor Engine Performance
"Excessive idle time can cause poor engine performance". This statement is out of the Cummins manual. See the attachment. When running my engine periodically when being stored, I knew to keep the rpm's over 1000; but this is tiresome to the foot.
There is a built-in feature for setting faster idle speeds; probably half of you know and the other like me awhile ago, didn't.
With engine running, in neutral, parking brake set; put the cruise control to ON. Tap the cruise engage button once and the idle goes up to around 1,100 and stays there. Tap it again, and it goes higher. Tap the Resume button and it goes down,
This is a great most over-looked feature. In cold weather, it can be used to warm the engine up a lot quicker. I always start at normal idle first for a few minutes, to get everything oiled-up.
