Ok so my car has been idling crazy high (4k +) ever since I put on my new intake manifold (AEBS). Ive replaced my IAC,TPS,PVC valve, Intake manifold gasket... adjusted the sqrew on the throttle body... Made sure there were no vacum lines unplugged.. basicly everything I know of to do. I also put a B20 throttle body on the car but I used the old gasket... So that maybe one thing but I doubt it could take in the air needed for the current idle.

I was told that the fast idle control valve could be removed with no problems on a B16a so thats gone.... Could that be the problem? Also I know trying another ECU is a good test but I dont have one soo. Thanks for any help in advance.

BTW- Its a 90 ef sedan with a b16a thats obd0
