Just talked to Freightliner and as I suspected...."fast Idle" is a programmed feature. It can be "enabled" or "disabled" on the ECM. I will have to go to a Cat engine place or a Freightliner place that has the CAT software to see what state mine is in. I'm betting that it's turned off. Freightliner said that sometimes when the ECM firmware is upgraded the Fast Idle will revert to the "disabled" mode, which is the "default" position. Thanks for all the comments. Rook
