I have a s1 rb25 with a greddy intake and q45 throttle body and a fmic. its running super super rich...

Fuel mixed with oil

rough idle... (after reving up, it is not able to catch itself, goes very low then back up and fluctuates)

cutting out... (during driving when I get into it sometimes it will cut out and I will have no throttle response whatsoever, but it doesn't happen everytime)

My q45 throttle body seems to be missing the iacv? Im not sure where it even goes...
Anyone have pics for correct setup?

Any ideas why its running rich?

Any help would be greatly appreciated

The iacv is on the intake manifold, stock and greddy
Do more research on your vehicle and engine setup, it's just nice to have.

because the only way fuel can mix with the oil is through the head gasket????:wtf:
