It occurs to me that, when the wheels are turning, it would seem that the ECM is keeping the engine revved up in order to provide for a smoother clutch engagement. I've had two manual Crossfires and I believe they both did this unless you do a throttle reset -and as soon as the system re-learns, it goes back to doing it.

What I am saying is that I believe this is normal. The ECM KNOWS the wheels are turning, it even knows how fast they are turning, the brake controller/antilock computer tells it what is going on. Remember, the stability control system has command of the throttle.

I really think this is normal. My Ford Ranger even idles high with the clutch in when moving.

Note that, when I posted here years ago, all I responded with, was "Your battery is too old". If you read my post, I said nothing about his actual complaint, mostly because I don't think his complaint is valid.
