    2012 hisun 800 idles high

    Hi i have a 2012 hisun 800. And it idles to high. I cleaned the throttle body and it still does it. Is there a sensor or something that could be bad on it? Thanks

    I take it you have some slack in the throttle cable so the butterfly can close?
    There is a sensor on the bottom side that allows more air in at idle-off idle but normally they stick open and cause low idle and stumbling ,engine dieing. Could look at that. Check for a vacuum leak. Plastic intake and tight on the jugs.
