Exclamation Changed Plugs and Wires Now it idles high

Ok, sorry about didnt know how to emerge threads, so i deleted one and whoops its all gone...i was talking about in my last thread about how i changed my plugs and wires and now high idle...i readjusted my idle screw and it ran fine for a day now its back to idle about 12 to 15 grand...would gapping plugs wrong make this happen? No vac leaks. TB clean as can be. What else possible could this be,. timing is right also....
__________If i unplug one hose towards the top of the intake, the idle goes down and idles right. its a tube coming off the upper intakemanifold to the intake its self. also has two screws beside them...what is this called?? could this be one thing to check in?
