in the process of gettin my civic ready for boost and converting to obd 1, im tryinh to run a 2 wire iacv without the use of an obd1 intake manifold or y8 intake manifold....

so i made a plate where the iacv will bolt too and screwed fittings into it where the passages would usually be on the maniofld.

i routed one to before the TB, and another to AFTER the tb....inside the manifold (with vaccum lines)

I got NO CELS, but i have an extremely WEIRD surging idle problem.... from 1000 to 2000rpms up and down....

i checked all my wiring everything is rite.....

and its not my maps (uberdata) cause i tryed more than one, and its not the iacv itself cause i tryed 2.

HELP PLEAS ANY INPUT!!!
