Intermittent idle surge when warming up when brake is pressed
O.K, noticed this about 2 weeks ago. When my truck is cold and running when I push the brakes the idle does not surge. But, when my truck is fully warmed up it does not do it either. But, when my truck is partially warmed and the brake is pressed the idle will start to surge 500 rpm (of course while in N or when the clutch is pushed in) I heard my idle could be too far up? (Idles at 1100) and something about my coolant becoming a certain temp and the sensor on the bottom of the butterfly assembly read the warmth of the coolant and then changes the idle...is it that thing?
Thanks
Thanks
