i am in need of a ssv valve and actuator

Hey fellow rotary heads. I have a 2004 6spd rx8 with a a.e.m intake , stainless midpipe with cat delete , under drive pulleys . I really think something is wrong with my car. I keep getting a misfire in cylinder two code. I have replaced all my ignition parts. I have tried seafoam. So I really think I need to replace the ssv actuator. It feels all loose and broken when I took upper intake manifold off and

looked to see if I could manually turn the ssv to open position. When I press my gas pedal to the flood my car struggles to climb through the power band. Does anyone have the parts in looking for?
