Mini me swap, troubles
 

Hey i was going to do a mini me swap on my 96 civic hatch,long story short the Y8 head did not work out, so i put the Y7 head back on and hooked everything back up with just a few aftermarket parts. Edelbrock intake manifold, obx header but thats basically about it. Now my problem comes when i start it up the car, it just revs out of control sorta like its a wide open throttle, but its not... the throttle plate is completely closed.... i have no idea why its doing this! any help would be great thanks
