    This also just started happening to me. I had to do a double take to ensure someone wasnt revving my car.

    It also has something to do with the outside temp. Almost like the choke on a carb engine. The warmer it gets outside the less it will hi idle

    Yes same here it’s not all the time but can definitely tell it went up then down.

    Don’t read into it.

    If it actually surges up and down and doesn’t settle then there’s an issue for sure.

    Pretty sure that forged internals and a supercharger would fix that.

    ^^^This

    It was doing this last year when it was warm outside (being a little erratic)
    But during winter, when it was cold, never an issue. Loud cold start, hi idle and then calmed down to idle after a little bit.
