i need help!
 

I have a 1991 mazda rx7 gxl. i need to know where the hose goes to from the idle control valve. if anybody has a pic or can describe it to me, please do. I would greatly appreciate it.

i know where it goes on my S4, but im not 100% sure about an S5. BTW Where are you from in tennessee, i live in the tri cities which is upper east tennessee.

You're talking about the BAC (cylindrical thing on the intake manifold), right?

If so, It comes out from the back of the water pump housing, goes into the BAC, exits the BAC, and goes into a nipple on top of the rear iron.

i live in franklin, tn close to nashville area.

sweet, i love nashville.

there are links to download the free factory service manual in the FAQ at the top of this section. it shows in detail where every hose on the engine goes.
