Ok, thanks to everyones help, with a modifyed acv, and 1/5th a tank of denatued alcohol, my car passed tailpipe with flying colors (i actually probably didnt need the alcohol, but better safe then sorry) only problem,.. egr diapram is dead. I tried to fix it allready once with lots of gasket seal, whihc i baked on in the oven, and it was sealing out of the car, but once on the car, apparently, it doesnt work. Ive been to 3-4 junkyards around here, and every single EGR diapram is dead. So what do you S4 Guys do for smog? is there a place cheaper than the 300$ mazda wants? is there a shop in the bay area that doesnt look at the thing? If i put on an 89 intake and a block off plate, do you think theyll be stupid enough to think its an 86' s5? say i plug the thing with JB weld so it will hold vacume? do you think the'll fail it when the RPMs dont drop? do i have any options but forking out 300 bux for a tiney piece of poorly engineerd rubber and aluminum?

 

Yeah they will fail the EGR if it doesn't stall the engine when they pull up on the plunger.

 

It's to bad you had to resort to rigging up your emissions control system to pass. I could have sold you a brand new EGR Valve I have sitting around.
