Really bad brup idle after tb and intake manifold upgrade


New Member
So I just upgraded my intake manifold to a skunk2 pro series and throttle body to skunk2 alpha tb 70mm and I’m not sure why but when I start it, it sounds like a rx7 or a nasty cam. I don’t know what the problem is cause I just got back into civics not long ago, but the car is also auto transmission and I didn’t have anywhere to plug the idle control plug cause there is none in the new tb along with the emissions line. does anyone have any idea what the problem can be? If you have questions I have answers

And also I scanned for codes and only got idle control valve code

Revving it doesn't help, can you just let it idle so we can here that?
