The liitle plug on the bottom of my throttle body(idle mixture?)fell out.I put it back in but it is to loose to stay put,it keeps vibrating back out.Ther is a mustang junk yard 20 minutes from my house that has a cobra throttle body for $75.00.will the throttle cables work on thisone? Thanks in advance.

is it possible for you to take a pic of this? Myself as well as some other people have had problems of vacuum leaks and come to find out that there is no plug in the bottom of the TB, and the service manuals don't talk about it! I found a bolt that fit and plugged it up but I'd rather fix it properly.
 
I already put it back together and am on my way home,but right in the middle of the bottom is a hex head screw,It has an o-ring and threads but also is shaped like a bullet on the end that goes into the throttle body.It protrudes up into the air bypass slits in the throttle body,as though to control idle air.It looks to have had some kind of glue or locktite at the head.Must be calibrated at the factory and glued in place.I screwed it back in to where the glue stopped and crazy glued it so it wouldn't back back out.It made a serios vacuum noise when out,but ran fine.It actually sounded as if it were coming from under the intake manifold.
