Mach1Canuck shows over on the mach1regisrty how to fix the hanging or slow to return to idle rpm problem. Click here for his instructions So I thought I would give it a try. And sure enough it worked! Finally. He said you need to remove the shaker, but you dont need to. I made my plate out of some aluminum roof flashing just to see if it worked. I have the ability to make these out of alumunium or stainless by the thousands in a matter of minutes where I work and any thickness. Anyway here is 6 pics of the install.
