i just put a h23 intake manifold on my f22 and now that i finished doing it my car idles from 1-2 and yes before i put it on i cleaned everything and replaced all of the vacuum hoses can someone plz help me oo yea when i shut off my car it shakes really hard

 

i would have to say that its in ur IAC iddle air control, it seems to just be revving high you should check ur iddle screw on the throttle body or maybe ur iac needs to be replaces

 

you have a vaccum leak somewhere.
could be iac, vaccum lines, or gaskets.

 

Next time it starts idling up and down, take off the pipe for your intake and put your finger over the lower hole in the throttle body to cover it up. If your idle returns to normal it's your Idle Air Control

 

alright i just tryed covering the hole but it just made it wanna die so i guess that works and i checked all of my vacuums and retightend all of the bolts and still nothing, i was wondering if the vacuums are in the wrong spots or would the coolant lines do that? also i see white smoke commin out of the exhaust. and is the coolant lines supposed to be hooked up to the tb?
