ok i bought a new manifold its like a blox replica, i am no longer running a iacv bc there is no where to put it on the manifold, well when i go to start it, it starts but it revs all the way to redline, i have to kill it, whats going on, thank you for your help

 

you have a have some kind of vaccum leak. running without a iacv will also make it run shitty. is your motor and ecu obd1 or obd2? maybe get a used blox manifold or S2 instead.

 

how is your idle being controlled without an iacv? also you need to check the vac ports like the above stated. there is no doubt that you have one

 

Please post pictures of the manifold that you are using, so we can help you...there has to be ports back there!
