So i figured out that IAS is the secondaries controller, only problem was that i didnt know i had a problem with them unitl i ran tests this morning... im thinking maybe last time i took off the manifold i mixed something up, but that cant be it since you dont need to take off that to remove the manifold... i know both wires needed to be re-soldered awhile back since they were hanging by a thread (did that myself) and they worked properly. but what coudl have gone wrong? the bottom vacum port goes to the manifold and the upper one goes to the Can on the back of the Manifold... right??... do i need a new IAS? I imagine they dont just sell them at autozone... where do i get one?


EDIT: I also failed emissions... horribly on the CO (49 instead of 15) and not as bad on the HC (1.4 instead of .8) this couldnt be the problem... could it?
