Is it whistling, or something vacuum related not working? You can try spraying a SMALL, CONSERVATIVE amount of ether starting fluid in the vicinity. If the engine speeds up, you've got one for sure! If you're already sure, please disregard. Many times the line at the rear of the manifold has cracked. Lets hope that you just forgot to plug it back onto the manifold. It's pretty easy to R&R the intake. If doing it alone, some people have used clothespins to hold some of those bolts up out of the way, so you can lift and slide the intake up off the engine without snagging anything. Another "while youre in there", is why not replace the oil pressure sender, if you haven't already done so........
