A trick Ive used that has always worked for me is to take a can of starting fluid and with the truck running spray a SMALL amount of the starting fluid around all the problem vacuum leak areas on the engine one at a time. Spray a small amount and wait a second and if the engine idle speed changes than thats where your leak it.

Maybe you got one of your plug wires crossed.
