5.4 cold idle start up
I have a 5.4 and when started cold... it revs to 1700rpm and slowly comes down to 1000rpms. Is there an adjustment to calm down the initial start up rpms?
thanks!!!

I don't understand the necessity of the high revs on a cold engine at start up. Thought there may be and adjustment or if in the PCM, maybe could get flashed to something more like 1300 or so.
you would think this would be hard on a cold engine!
