Throttle servo horn slipping

So my throttle servo horn is what I think broken as when the brake is applied then when the brake is released, the brake go back to neutral but this then engages a small amount of throttle and I’ve tried everything with my servo horn from tightening to loosening to even putting oil on the metal ring to make the throttle slide easier but it won’t work has anyone else suffered this problem or can help me solve it ?
