So I finally figured out my idle issue but now I'm really stumped.
The iacv is blowing air out of its inlet. what will cause that to happen??? The engine is a early ej20g being ran by a ej22t ecu and sensors I'm loosing my mind.

This is the three wire IAC valve correct?

Does air coming out feel like a pulsation, or is it a steady stream of air coming out?

This little check valve

may be installed backwards. This is assuming the ej20g has a similar setup to the ej22t motors

It's a steady blow, I have checked the check valve it seemed to be in good shape. I supposed I could go get another valve and try it. The ej20g and ej22t iacv are very similar. The only difference is the inlet tubes clocking and length of the tube it self.

On another hand with this problem is the iacv inlet hose if I disconect the hose it won't cause the engine to stall, the engine will raise the rpms. Thanks.

Are you sure you installed the check valve in the correct orientation?

What's your vacuum reading in the intake manifold? Honestly, if you have a vacuum reading in the intake manifold, I don't see how you could have air blowing OUT of the IAC valve.
