hey guys whats up yesterday me and my friend decided to put his si intake manifold on his hf motor to see if it made a differanc we extended the sencor to the back of the manifold and hooked up all the sensors and cranked it up it shot up to 5 grand and stays there ocasionally going down a little but shooting right back up does anyone know how to fix this any help would be great

 

did u adjust the thottle cable? but the other thing is it sounds like u have an open hole somewhere in the intake manifold like vacuum line connection or vacuum lines crossed lemme know

 

yeah we adjusted the throttle cable we hooked up all the vacume lines but on the si intake manifold there were two places were a hose needed to hook up so we just connected them togeather
