It's been sticking between 1-15% lately (lately as in past year).. and I kept trying to adjust its position so it doesn't contact the edges of the bore, but since then, it just got worse and now it apparently wore down the top edge of the blade so air goes by that shouldn't, causing me to have a nice vacuum leak and an IAC valve that is fully closed and ineffective at idle.
I have spare throttle bodies but 52mm stock ones. My throttle body is a 62mm RSM one.. I have a post on my local forum seeing if anyone knows a place that can fix it, otherwise, does anyone know of a place I could send it to for repair?
