were you able to repace all the missing and damaged parts to your throttlebody?
maybe your regulater is bad.
what i would and did was to go to the junk yard[ my
favorite place] and buy a complete tb. clean it and get a seal kit and put it on. only cost me $50, to do that. while youre there get a canaster.

I know this thread is a few weeks old, but I wanted to comment on this. The regulator doesn't know how much fuel pressure you have, it only restricts the the flow depending on engine speed. The regulator will drop the pressure 3 - 10 psi depending on the amount of vacuum applied. If he has a 60psi pump the most the regulator would reduce it to would be 50psi.
