Exclamation hight idle when cruising in neutral to a stop

well this started happening when i installed my volant setup, but i dont think the volant would cause this, i also recently installed some arh lt headers, but i had the headers checked for leaks and everything was ok, i installed a fast 90 90 setup last year, i think the fast is leaking but i have no idea from were, can anyone give any input

sounds like an intake leak . just start with what is easy then work the way up . try your idle screw on the tb closed all the way , check the tb bolts , air /egr if you got it / could be a vacum hose on the back of the intake , might even be one of the intake runner gaskets on the bottom of the intake .
good luck and post up when you find out what the deal is .
