87 5KCSTQA Throttle body air leak

[Paul Meyers]

I seem to have a rather massive air leak that looks to be coming from the
shaft of the throttle body on the engine (right) side. I have replaced the
throttle body gasket with no effect. Anything I can do besides replacing the
throttle body? Any experience with this would be helpful. I replaced the
injectors and, while I was at it, cleaned the throttle body without
disassembling it (carubrator cleaner). The throttle body has replaced the
injectors (replaced) as the source of boost (vacuum) leak. 

What to do?
