Bradley, Numerous people on the list advised me to crank this connection down tight. The ears of the throttle body and the intake plenum should almost come into contact. Like you, I replaced mine in the process of fighting a manifold vacuum leak. I think I still have a leak. You've done a thorough job replacing possible leak sources! You've probably already considered these other sources but since you didn't mention them don't forget to examine the brake booster, auxillary air regulator, and distributor/fuel pressure regulator vacuum circuits.
