2012 sport high idle at start up
2012 sport 5.0 motor.
At start up( cold or warm) the RPMs go to 2k for a few seconds, then to 1.2k for approx 25 seconds then settle at 750-800.
I have cleaned the throttle body and reset adaptive values with no change.
Had the intake off with ignition on while my wife stepped down in the pedal smoothly to check the butterfly movement. Seems a little stalled at the beginning of the sweep, but if it is, it's so minor that I'm doubting that's what I'm seeing.
Any thoughts?
