AC&CV removal problem
 

I have already read most of the idle problem links using the search option.
My idle was fine then i took off my ac&cv, i used the block off plate and lots of RTV gasket maker. There is no vacuum leak there. I screwed down the idle adjustment screw on the TB all the way down. My idle is at 900-950. Whats my problem? Its got to do with the ac&cv nothing else.
