Ssv

So I just became a member but I have been following the page for sometime now as I have had my RX-8 for over two years, but I recently came across an issue my SSV is stuck closed and the dealership refuses to clean it so I either need a diagram on how to do it myself or any other rotary mechanic near Jacksonville North Carolina, i've done research and fixed everything that I can but the SSV valve is still stuck closed resulting in a loss of power after 4000 RPM if anybody can please respond as soon as possible oh yeah and it's a series 2 please
