Lately I have been having trouble with my h22a for some reason the idle will be high and it will eventually taper down and die. I noticed that if I pull back on the gas pedal the car will die? It seems like when the throttle plate closes the engine dies? I was thinking fast idle valve? I dont have all of the vaccum ports hooked up on the intake manifold but I have no leak whatso ever. The only codes im throwin are knock sensor? Any suggestions? Iacv is hooked up and working properly? If the throttle plate is closed should the car die or is that adjust with the idle screw? That hasnt worked either

 

Wtf. You think you could explain this?

 

well maybe I was hoping that I could get away from it........I hate hooking up vaccum bs
