Ran a pressure leak test.... Wow she leaks like crazy! Both gaskets at throttle body I am replacing. Leaked all around those. Didn't hear many other leaks besides those.
Just used this set up and sprayed the vacuum lines and manifold with soapy water. It bubbled well where leaks were. Worked very well.
