R P M 's How Many

   / R P M 's How Many #2  
My 2006 CK20HST idles at just over 1000rpms. Your manual should say the correct idle speed.

1100 is about right
 
   / R P M 's How Many #6  
I only use that low idle for actually starting the engine and then for only a second before shutting off. All the rest of the time it is at about 1300 or above. That diesel sounds much happier with a couple hundred more RPM.

The tag on the engine valve cover also lists the slow idle RPM and mine is a hair over 1000.
