Almost positive it is sticking or faulty cause when I apply the brake at idle the revs drop about 300rmps. Does anyone know how much one is from mazda or does anyone have a fully functional one for sale?

Well, clean It. First remove the BAC Valve. Scrap all gasket off It leaving a clean mating surface for reinstall. Give It a shot of WD-40 and allow It to sit In the opening momentarily. From there, I rigged up two 18awg wires with two 1/4" female connectors. Apply 12v from the Battery to really work out the crud In the Valve. Do this a few times and end It with compressed air blowing out the residue. Reinstall (with new gasket) and observe for any differences.

I followed the same procedure - at a time of not needing to. I did this as a reprocussion, or a "just In case" type of deal.

If it is broke cleaning may not do any good. I'd suggest you test it per the FSM first.

Also, the following is a BAC cleaning how to.

That howto is for a turbo, is it the same for N/A?

For my S5 NA I had to take off the intake hose that wasnt letting me get to it, then you take it off I think 12mm wrench 2 or 3 diff bolts, then I sprayed all the opening with intake cleaner and let it sit then I scraped any left over sticking crud off, there is also coolant hoses connecting to it, you might want to pinch them with something or things can get messy

TII and N/A BACV's are interchangeable.

Yep, the howto will work for both.
