Upon start up, the car will rev to 3500 and hold there. If I pull the hose that connects to the throttle body intercooler piping, the place where it"Y"'s off to the rubber hose it drops to about 1700 and idles lower.
I adjusted the idle air screw all the way closed and it was the same, I opened the idle air screw all the way open and it stayed the same. I have to pinch or plug the rubber hose that runs to the Y on the intake side intercooler piping to keep it at 1700 otherwise it jumps to 3500. Am I missing something, I checked for vacuum leaks and came up blank, the GReddy intake manifold is plugged up with caps, I cannot figure it out.
