Terry,
As others have said, it's probably one of the connections under the plenum. If/when you pull the plenum, also check the fit of the injector in lower, primary o-rings. if the fit is not snug, vacuum can leak at this location also. That o-ring is in a groove, inside the injector housing.

Hope you find your problem easily.
