HOT Start Problem Still UN- Resolved..FD???? 86,5KCSTQ

     OK I was almost positive that new injectors would do the trick. NOT 
     SO! The guy at the Audi shop was telling me my problems before I could 
     get the words out of my mouth. He said you need injectors and sounded 
     SO confident that I look no further and just bought em'.  
     
     Anyway we are now down to one of two things, Fuel Dist, and/or bypass 
     valve.  Lets eliminate fuel pump, check valve. The pressure is there! 
     and how! The problem is that the Throttle plate is not picking up when 
     started hot... I can take the air cleaner off bring the car up to 
     temp, and get it so that it doesn't start and all I have to do to get 
     it to start is lift the plate, Now I know there's vacuum there, enough 
     to lift the plate, but In a hot condition something is telling the 
     Fuel Distributor not to provide fuel. Is it sticking? I tried Jamming 
     a plug in the top of the air boot (Commonly referred to as "MR PEANUT" 
     by my ex-girlfriend)  and it did start but still sputtered. 
     
     ANYBODY BTDT??? Its thermally related...... Why ???? I need a better 
     book!!!
